Hi crabbya, the people that you are researching should all in a book called:
Family history of the Donnellys and the Crushells of Belmont, Co. Galway by Fr James J Donnelly.
I read it some years ago because I was researching Margaret Devaney's family. She was one of the Devaneys of Lissananny, Kilconly, Co Galway. She was born in 1819 and died around 1911 (daughter of David Devaney and Mary Connell). She married Michael Hopkins who was from Russelltown, Miltown, Co. Galway. I never took down who their children were at the time but I'm certain that their descendants were listed.
