Re: Dawson from Ireland to Western Pa.
My gggrandmother was Mary Jane Dawson Frew who immigrated from Ireland in 1850. Her birthdate is conflicted; 1900 census says 1840 and her tombstone says 1834. I have not found her parents names yet. Her sister Eliza shared her residence as a widow in 1900. Eliza's married name was
Wilson. I don't think the two girls were twins.
