Some time since you posted your message! Today is the first time that I have browsed the genealogy.com forums.
Your grandmother Ruth ALLEN HAY is the sister of my husband, David ALLEN's (DHA) grandfather Rev William Herbert ALLEN known as Henry Herbert ALLEN. That makes you second cousins...I think.HHA conducted the funeral service for Brian HAY.
HHA, Ruth and siblings Arthur Thomas, Clara Louisa and William Charles are the children of Charles ALLEN and Catherine DRISCOLL. My researches have been guided by information from your aunt Elaine HAY CAMPBELL (EHC) in a letter to DHA's cousin John ALLEN. EHC acknowledged the assistance of Margaret ALLEN GREGORY the grand-daughter of Charles ALLEN's brother John.
I have a more information than the above but would very much like to compare notes and learn more about the family. As luck would have it, we were in Launceston for 2 weeks in January 04
