I recently learned that my grandfather's mother was a Mulhall and his father's last name was Nolan. I found him in the 1910 PA census. His grandmothers name listed was Mary Close 56- head of household; son John Mulhall 38; dau Sadie 28; grandson Donald Nolan 14 (my grandfather); and another grandson Leo Mulhall age 7 who I am told eventually became mayor of Shenandoah, PA.
I don't know when my grandfather changed his name to Mulhall. I also don't know what his mothers name was. I have heard that his father (Nolan) was possibly a General in the US Army and worked in Washington DC. If anyone has any information I would apprieciate it. My email is firstname.lastname@example.org
