Patricia
My Paternal grandparents were William Dalton and Alice Cahill. The William’s Grandfather and Great Uncle (Dalton) left NL for NB in 1818 (married Mooney sisters). I am not sure where they lived in NL but were from Queens Ireland originally. I have no information on the Cahill’s. The earliest I have is Richard Cahill and Bridget Cronan listed on a marriage record for my Great Grandparents in 1872 (Halifax). I know that the Cahills were liquor dealers/grocers/hotel owners in Halifax (late 1800’s thru to 1950’s).
Have you or a family member had their DNA done? I have so we could see if there is a match
