I am trying to trace my PERDEAUX/PURDEAUX O'CONNOR family in Ballineen, County Cork. I know this is a long shot and your family were not Catholic.However... I have a baptism in the Catholic Church at Enniskeane which is the twin town of Ballineen and the church were Ballineen Catholics attended.
bap. 21 Dec 1855Michael O'CONNOR son of Michael O'CONNOR and Mary PURDEAUX Sponsors -John and Mary SHORTEN
Do you know if a "sponsor" was a godmother or godfather?Is there a remote possibility that these SHORTEN couple are related to you?
