Well, I was also responding to this thread about McLaughlins in Renfrewshire. My gr-gr-grandfather, Dominick McLaughlin, did emigrate from Derry, but married and remained in Renfrewshire until his death in 1901. I don't know if other members of his McLaughlin clan followed him to Renfrewshire, but I do know one of his brothers was in the area for work for about a year, then returned to Ireland. Dominick married Bridgett Kerr in 1871. They had 2 daughters, Jane and Mary, who both pre-deceased their parents and never married. I will go back to my prior McLaughlin thread to pursue questions I still have about this family, thanks.
