Hello,
I too descend from the McLaughlins from Malin Donegal.Their nickname was White Paddy.
The Charlestown section of Boston (only one square mile) consisted of a vast majority of Donegal natives.Brookline,Ma was/is a wealthy suburb of Boston,many Irish first lived here working on the estates .Often when a young couple married they would settle in Charlestown to begin their life.
Many Charlestown Irish as they did better would move to the suburbs/areas north of Boston.
(Medford,Stoneham,Wilmington,ect.)
In the 1930's Medford was begining to become the Italian enclave that is today.Many Irish Americans moved further north to Reading ,Ma and Andover,Ma.
Andover once a farming community-middle class has in recent decades become a wealthy place to live.Middle class(Grand Children of the Irish have now moved to southern New Hampshire (Windham,Derry,).I am just trying to give Gracelands some clues as to where her American relations might be!!!Let me know if I can help.
