We're including Belfast in our first trip to Ireland. I have been searching for more info on places in and nearby Belfast where my Irish grandmother lived before she emigrated to America.
I have a copy of her sister's baptism certificate, so I know her sister (close in age) was baptized at St. Malachy's Catholic church. There's more than one St. Malachy's, but this one is in Belfast. I found it! There's a web-site called www.inyourpocket.com . It has a section on Belfast. I clicked on churches and found St. Malachy's, built in 1844. So of course we gotta stop there while we're in Belfast!
Also planning to see the Belfast Botanic Gardens with their historic Palm House. My grandmother and her sisters liked to walk there when they were young. (Of course they did. I think they did. Actually I talked to my Dad's cousin who was able to take his mother (my grandmother's sister) back to Ireland to visit the house she once lived in with her siblings, and they walked in the Botanic Gardens and she said she remembered them, and that she and her sisters used to go there.
It's fun hunting for places with some personal history! Two of her brothers helped build the Titanic. They weren't allowed to tell anyone they were Catholics or they and their supervisors would have lost their jobs.
On the web-site mentioned above there are some cool things for Belfast. There's a list of "Titanic Top Ten" and also "Narnia Mania" because C.S. Lewis was born in Belfast.
It's wonderful that you have so much info about your grandmother. I know just walking in her footsteps will be a thrill. I really have to look into my genealogy when I retire. It just takes so much time and my relatives go back farther than even great grandparents. Plus the last names are pretty common. I know you will have fun in Belfast. You are even having fun just thinking of it and researching!
