I read your message and when I saw you have facts from mid 1700's
and mention of Pa., I wantd to tell you, my search is for Samuels, two, McKees. The father died in 1780, leaving minor children, so I guess he was born 1740-50, but I have no idea where or who is dad was. They were in Westmorland Co., Pa. Hempfield Twp., for a hundred years. McKees are so bad about using the same names, and I'll tell you, Charles is not one I ever run into, but Alexander I see a lot. I'm sure you know about the infamous Alexander who fought with the British, and his father was a trader.
I cannot find the immigrant, tho I think he came from No. Ireland, after Scotland. I've thoroughly searched David's family, the one at the ferry, whose son founded McKeesport, and I feel certain he had no Samuel, (tho some would disagee). I believe David was a brother of my Sam/ls father, but little is known of the bros. who came over together.
If you run into a Samuel
please let me know. Donna McKee.
