the names your ansestors have are very close to my families names. thinking they could be related. my james mcginley came from county mayo. had relatives in pa. they lived in marietta ohio but i see some of their children were born in pa. my james was born in 1822 in mayo, his father's name was patrick. he named a daughter mary so i am thinking that they were related. your patrick could have been a brother but i have no way of prooving.
