I am trying to determine if a Jane Gorman (1829-1913), born in Tipperary to John and Johanna (Heffernan) Gorman, is the same Jane Gorman who married Cornelius O'Sullivan and whose son Cornelius (b. 1869) of Dunmanway is my maternal great-grandfather.

This John Gorman (1795-1867) was born in Limerick, and his wife Johanna (nee Heffernan, 1796-1863) was born in Tipperary.

Any help is truly appreciated!!
