William Hennessey and Mary J. Hennessey were both born in Ireland and came to New York, USA where in August 1876 they gave birth to a son, William A Hennessey in Manhattan, New York, USA. I believe William A. was my biological grandfather. His son, Michael J. Hennessey Sr was my biological father. I'd like to learn where I came from and where the family is in Ireland. My husband's family is from Ireland and we plan to go visit and hope to locate relatives. Thank you
ReplyI am trying to find ancestors in Clare County Ireland or wherever they may be in Ireland. My moms maiden name was McIlvoy.
