Just received baptismal records showing Margaret Mulroony b. 1850 was mother and Thomas Brennan b. 1844/5 was father to my grandfather, John Thomas Brennan. They had four children all born in Nashville - John Thomas, Sarah "Sadie", Laurence, and Edward between 1872 and 1878. Thomas and Margaret were both born in Ireland, but I don't know where. Can anybody relate?
