Dan --

Forgive me if I wax, proffessorily, but I thought to make this both pertinent to your inquiries, as well as enlightening (hopefully!) to all that might wish to research their roots.
You had mentioned having reached a 'Dead End' with your research, after finding the following:
Glaundahy
Dromtarrif Parish:  Jeremiah Murphy (born 1840, baptised 1842) son of Dennis born (1808)

I have spent some not insignificant amount of time, trying to ascertain the location of that Townland and am sorry to report NO success.    

According to the sources that I have access to, there is NO Townland extant, anywhere in all of Munster.

THAT is the BAD news.  The GOOD news is that just because there is no record of such an area, it does NOT mean that it doesn't exist. 

Can I hear you say, "WHAT?"???    

Let me give you an example:  My wife's Grandfather was born on 23 June 1880, in Ivale, Kilcorney, County Cork, Ireland.  We KNOW this, as we have a signed and Officially Sealed, long-Form Birth Record to PROVE that it is so.

The problem is, the Townland of Ivale also fails to exist, according to those same sources that likewise deny Glaundahy.

Now, I have walked the byways of Ivale, gazed across the green, munificent fields at the grandure and SPOKEN with living, local residents that have assured me that I was standing within the confines of Ivale -- yet, the Ordinance Survey Map of the area (#79) and all other references refer to that area as Brookpark.

This, in spite of the very energetic effort of the Irish Government to revert all placenames to their original, Irish wording.

Some BASICS, first:

According to my digitized copy of 'Francis Guy's County And City Of Cork Directory 1875-1876' , County Cork encompassed 2,700 square miles, 1,849,686 acres and was 110 miles East to West (Youghal to Dursey Head) and 56 miles North to South (Charleville to Old Head).
The county was made up of 23 baronies, 243 Civil parishes, 5,478 Townlands, 14 Poor Law Unions ENTIRELY in Cork and 5 others that were shared with other Counties.
Cork was also divided into 3 Dioceses - Cork, Cloyne and Ross.  Additionally, the parrishes of Drishane, Cullen, Dromtarriff, Kilmeen and Nohavaldaly were in the Protestant Episcopalian Diocese of Ardfert and Aghadoe.  Those five, PLUS Kilcorney, Killaconenagh and kilnamanaghare are ALSO in the Roman Catholic Diocese of Kerry.

Population, according to the Official Census Figures:

Year                      Inhabited Dwellings                 Persons

1831                            118,879                        810,732
1841                            130,283                        854,118
1851                             93,557                         649,308
1861                             86,598                         544,818
1871                             84,789                         517,076

From those numbers we can see a HINT of the devastation that the Famine caused. Whole communities may well have disappeared.  Then, too, DESPITE the obcessive penchant for record-keeping by the English during their rule over Ireland, SPELLING was NEVER a high priority!

 {NOT THAT I AM IN ANY POSITION TO THROW STONES ON THAT ISSUE!!} 

As a case in point, my wife's Great-Grandfather had 13 KNOWN children and we have obtained birth records for many of them.  All that we have were recorded by only TWO men (John Leader, MD and his son, Richard Radley Leader, MD).  In the space marked "Mother's maiden Name", the spelling of her name (Lehane) varies, from child to child.
It appears as 'Lehane', 'Lyhane', 'Lehayne' . i once met an elderly man who told me that his father's Birth Record gave the surname of DOODY -- yet the father's brother, only a few years older, was recorded as Dowd.  Such was common, as the Anglo-Irish Registrars attempted to WRITE - in English -- what they HEARD -- in Irish.

As I said, I attempted NUMEROUS spellings and permutations of Glaundahy -- with NO results.
From the website 'HELP' page:

"Please be aware of the notice on the IreAtlas search form page indicating that the search engine on the IreAtlas Townland Database has been modified to produce a much faster search.  This increased speed can only be obtained when using the "Search Method" of Must match EXACTLY.  Be aware that the "Search Method" has been modified to make this the Default "Search Method".  You must also be aware that this method of searching IS case sensistive.  This means that you MUST enter the townland with the first letter as upper case and the remaining letters as lower case or your search will fail. 

 After having the IreAtlas Townland Database online for over 6 years, it has become very evident that the one issue that is a major roadblock to most researchers is the issue associated with spelling.  I will not go into detail here in this page as to what has caused these spelling issues, my intent is to make the researcher aware that they exist and that they MUST be considered when you do not get the expected results from your search.  To add further support to this statement, I can tell you that more than 95% of the requests that come in to me for assistance in finding a researchers "elusive" townland, have resulted in the townland being spelled different from the way that the researcher entered it into the search engine.

 This issue of spelling was known when the IreAtlas townland database was designed, and it was because of this issue that the search form has been designed with the dropdown selectable choices for the "Search Method".  An observation that I can pass along to the researcher that is using this database is that the spelling issues that I have been asked to assist with are generally small spelling differences that many times only involve one or two letters in the submitted placename.  This condition can easily be worked around by entering just a few of the letters in the spelling of the placename from the beginning or the end of the placename. 

Sometimes as few as 1 or 2 letters may be required to get around the spelling issue.  If you enter a few letters from the beginning of the placename, then you would select "At BEGINNING of field" from the "Search Method" drop down menu.  If you enter a few letters from the ending of the placename, then you would select "At END of field".  To make your task a little easier,  you should make sure that you click the small "Sort By" box next to the Townland field.  This will order the list of returned townlands alphabetically and allow you to scroll through the returned list in an orderly fashion.

 The researcher should be aware that this method of searching will return a much larger list than trying to search using the exact spelling, however it is far better to get a list of possible townlands that you can select from than to get no list at all when you use the exact spelling and your spelling turns out to be wrong.

 The following is a few examples from county Roscommon that you can use as a guide that will help to demonstrate these spelling issues

  USER'S PLACENAME DATABASE SPELLING ENTER FOR BEGINNING ENTER FOR ENDING COMMENTS
  Loughglyn Loughglinn "lough" "glyn" "glyn" would not find the placename,
  but "lough" would
  Gralla Grallagh "gral" "la" "la" would not find the placename,
  but "gral" would
  Cloonacarow Cloonacarrow "cloon" "carow" "carow" would not find the placename,
  but "cloon" would
  Lislee Lislea "lis" "lee" "lee" would not find the placename,
  but "lis" would

  And of course I would be remiss if I didn't point out that you could be one of the remaining 5% who have been given the name of a townland from a family member, and it is completely wrong.  This situation can result in no records being returned at all.  There is absolutely no way that I can help you with this situation, it is going to take additional research on your part in order to move forward with your search. 
 
I can not emphasize enough the number of times that the simple spelling issues have resulted in an email coming into my mailbox.  It is with deep regret that I must inform the research community that I will no longer be able to respond to these type of requests for assistance.  As mentioned above, the search engine has the ability to perform the search even when you are not sure of the complete spelling. 

The administrative tasks associated with the normal maintenance on the Leitrim-Roscommon server have reached a level that make it impossible for me to respond to these requests for assistance.....there is only one of me, and so many of you!

  I wish you all good luck with your research"

                                                                                                       

I DID find also find THESE references -- BOTH reference the SAME book -- :
 
  http://www.ancestry.com/learn/library/article.aspx?article=2292
 
 
  http://www.ajmorris.com/roots/catalog/0040.htm

  GENERAL ALPHABETICAL INDEX TO THE TOWNLANDS AND TOWNS, PARISHES, AND BARONIES OF IRELAND (Based on the 1851 census). 968 pages.
  Originally published by the Stationary Office, Dublin in 1861.

 "This is an essential reference work for Irish genealogists, listing all of the townland names in a single alphabetical sequence. The Irish townland is the basic geographic division into which all parishes are divided. There are over 64,000 townlands in Ireland, each averaging just a few hundred acres or less. 
  It is essential to identify the townland of residence for Irish ancestors when doing genealogy because many land, census, estate, and other records are organized by townland. Also, it is often possible to distinguish between two persons of the same name in a parish only if the townland of residence is known. Once the townland is known, this reference work will give its exact location, citing a map reference, the size of the townland in acres, the county, barony and parish within which it is located, and the Poor Law Union it is in.
  This reference work also has a complete alphabetical list of the almost 3,000 civil parishes in Ireland, citing for each a map reference, size in acres, the county, barony and Poor Law Union in which it is found. Finally, there is an alphabetical list of the approximately 325 baronies into which Ireland was once divided, listing the map reference, size, county and Poor Law Union.

  SORRY! Microfiche Title No Longer Available."

The referenced book IS available, however, for purchase, from Amazon Books.  Price, NEW, is $60:

So most of what I've detailed shows what I did NOT find, my EXCUSES as to why I failed and what MIGHT be available.

Here is what I DID find -- (Again, according to Guy's Directory):

Four towns of interest, Geographically, to Murphy research are listed -- Kanturk, Dromagh, Banteer and Millstreet -- all within reasonable distance to Dromtarriff Parish.
  Town                   Significant Landowners    Address  or Townland

Banteer                      Murphy, John                         Killen
                                   Murphy, John                         Dromskehy
                                   Murphy, Laurence                     Glen south

Dromagh                   Murphy, Daniel (Reps of)              Clonbannin
                                   Murphy, Matthew                      Coolclough
                                   Murphy, Patrick                      Dromskehy
 Kanturk                    Murphy,Cornelius                     Farrandoyle
                                 Murphy, Mary                          Lackeel
                                 Murphy, Matthew                       Meelaherragh
                                  Murphy, Patrick                       Garrison
                                  Murphy, Thomas                        Kilcaskin

    Millstreet               Murphy, Andrew                        Knockduff lower
                                 Murphy, Cornelius                     Boolamore
                                 Murphy, Denis                         Ahane lower
                                 Murphy, Denis (Matt) * *              Coolykerrane
                                 Murphy, Jerimiah                      Coomlegane
                                 Murphy, John                          Coomlegane
                                 Murphy, John C                        Claraghbeg 
                               Murphy, John Denis                    Knockagallane
                               Murphy, John H                        Ballydaly
                               Murphy, Patrick                       Dooneen

  *  *  General rule of Irish Names / Nicknames is that if there were two different men with the same name, the man's father's name was added to HIS -- So, Denis (Matt) was PROBABLY the son of Matt.  This MAY also have been true of John Denis???

      I also found THESE Murphy listings in GUY'S:

     NAME                           ADDRESS                   EXTENT                    RATEABLE VALUE
Murphy, Thomas & John     Carragaige      57 acres 0 Rood 0 Perches    6 Pound 5 Shillings
Murphy, John T               Kanturk                      323      3      35          195      5
Murphy  John D          Knuckgullane, Millstreet         13      1       5              4       5
Murphy, Eugene              Dereen                              42      0      30           17      15

These were men whom either OWNED the land, or held leases in excess of 30 years.

Dunno how much this helps, or if it further muddies the waters???

I seem to remember that we discussed a Carragaige connection, at ONE point?  If so, that MIGHT be your best avenue at finding a 'Living Link', given the above info.

Bob

Dan,
Are you still looking for information on "Glaundahy"? I might have a lead for you...

Townland: Glandaeagh
Civil Parish: Killeentierna
County: Kerry

Glandaeagh looks to be about 15 miles from Dromtarriff, but over the line into Co Kerry.

The 1827 Tithe Applotment Books for "Glandasigh", Killeentierna parish list a John Murphy, perhaps father to Denis?? It is a fairly small townland at 633 acres.
titheapplotmentbooks.nationalarchives.ie/search/tab/results.jsp

By the Griffith Valuation in the late 1840s, no Murphys are listed in Glandaeagh.

The online index of Diocese of Kerry church records at churchrecords.irishgenealogy.ie :
I do not see the baptism of Jeremiah that you reference in 1842, but I did see baptism of several children of a Denis Murphy and Mary Foley in Dromtarriff. Is this your line?

Dromtarriff RC parish, children of Denis Murphy & Mary Foley:
Baptism of CATHERINE MURPHY of GLAUNDAEGH on 17 December 1843
sponsors Daniel Foley, Gobnet Foley
Baptism of TIMOTHY MURPHY of GLAUNDAUGH on 23 December 1845
sponsors David Hallanan, Abigail Hallanan
Baptism of DERMOT MURPHY of GLAUNDAIACH on 5 April 1842
sponsors John Foley, Mary Connell

Not sure if this is the same couple as there is a 7 year gap; recorded at Dromtarriff:
Baptism of MARY MURPHY of FORTGRADY on 4 April 1852
parents: Denis Murphy, Mary Foley
sponsor Abigail Foley
Fortgrady is a townland in Dromtarriff Parish.

I have Murphys from the Millstreet area which is very close to Dromtarriff.

Good luck
Keri

Wow!  What a 'Blast From The Past'!    

Glad to see you finding some possible leads.

Just 'Shows to go ya' that once it's on the Internet, NOTHING ever goes away!
