I have a Patrick Callinan who married Sarah(Sally) Stephenson (my ggmo's sister) in Gort, Co Galway in 1857. They had 3 sons,all born in Gort. Michael(b 06 Dec 1857), Thomas(b 03 Feb 1859), Patrick(14 Feb 1860). Evidently my elder Patrick died between 1859 to 1864. Do you know where and when your Patrick died? I also have a cousin living in Kilbeacanty Parish on the same farm owned by our ggparents, Michael Corless and Mary Stephenson. He knows of the Corless families in Kinvara, about 15 miles to the west but doesn't know of a direct connection.
