Hello! I live in Kingston, Ontario, Canada and have been researching my family for many years.
My Simpson Family is from County Antrim, Northern Ireland. They immigrated circa 1840s to Ontario. Family lore states 4 brothers --- Samuel, James, Thomas and Robert --- came to Canada, and 2 brothers --- names unknown --- went to Louisiana, USA, and possibly 2 more brothers stayed in Ireland. They are the children of Adam Simpson and Rachael (Rachel) McBride. I also believe the Simpsons originated in Scotland as part of the Fraser Clan; and pit stopped in Ireland for ~200 years on their way to North America.
I suspect there is at least one girl in this family as well, since no downlines I've found to date have only boys and no girls in them, except for my dad's 1st cousin, J.A. Gordon Simpson, who has only 4 boys (born in the 1950s and 1960s).
I'm descended from Samuel and James as my great grandparents are 1st cousins --- John (son of James and Mary Jane Nesbit Simpson) and Rachel (dau of Samuel and Jane O'Raw Simpson). Samuel was a weaver by trade.
Family lore also states that Robert went on to Toronto, Ontario and started the Robert Simpson Stores, with 23 stores, now defunct, that were purchased by The Hudsons Bay Company.
My 2nd cousin Stephen Simpson attended Mardi Gras within a group of twenty year olds about 1990 and met a Louisiana girl, last name Simpson, who was descended/related to the Robert of the Robert Simpson Stores in Toronto.
I believe there must be at least a thread of truth to this story!
