My father was Arthur John McLaughlin son of Jerimiah and Kate ( Hahn) McLaughlin. He was born in Brooklyn 1908. Parents immigrated from Ireland late 1800's
Sisters Jean (?)
Claire and 8 other siblings.
How can I find out what counties they were from??
All I know is that McLoughlin/McLaughlin is a popular name in Counties Donegal, Derry and Tyrone.
