My great grandmother's name was Anne Grant, b. 1854, d. 1934. She married Michael Duff in 1880. Her parents were Patrick Grant and Catherine Pattison, who were married in 1851. Patrick was age 27 when he married. He died in 1896. The civil death record stats he was 72, which puts his date of birth at 1824. He died in the workhouse, and was from Colt, according to the civil death record. His wife Catherine had already died. You can obtain that information at no cost from irishgenealogy.ie, which is where I obtained it. It's relatively easy to perform a search on that site.
In my family tree, I have his father listed as Patrick also, but I don't recall where I learned that. It might have been from a sacramental record. I calculated his date of birth at about 1800. He had a sister named Eliza. Again, I don't have notes re how I learned of her name. If you like, I can make my family tree on ancestry.com available to you. You don't need a paid membership to access it. Contact me if you wish to do that.
