Greetings: I’m trying to locate any information on the origins of my 6th Great-Grandparents. Archibald Thom(p)son is believed to have been born about 1691 somewhere in Ulster (County unknown), from Scottish lineage. He married Elizabeth (Betty) (Last Name Unknown) about 1717. They had a son, Robert Thom(p)son, born about 1723 in Ulster (County unknown). Archibald, Betty and Robert emigrated to the United States in 1724. They eventually settled in the Bridgewater & Brockton, Massachusetts area, where Archibald and Betty had 7 more children. I have extensive records on Archibald & descendants in the US, but I am unable to locate any online records regarding their Irish and/or Scottish origins. If anyone is able to assist, I would greatly appreciate it. Thank you.
