I've been wondering if Frederick Bott of Virginia was related to my Bott family of York County, PA; the Botts of PA were German.As I went through VA records (this has been some time ago), I found another problem, that some of the Botts there were British.The German name also changed for some to Butts/Butz, but without actual birth records to link these families, we may be out of luck here.
I found one Frederick in my line - Johann Friederich Bott, b. 2 Jan 1736, Chr. 5 Jan 1736 in Sonnenberg, Germany, son of Johann Emrich (b. 1702, emigrated 2 Sep 1743 on the Loyal Judith with brothers Hermanus (my ancestor) and Peter Bott, to York County PA. I haven't been able to trace this family past their birth dates, however.
If you think York County PA is a possibility, you might try contacting the York County Historical Society.They have a file on the Bott family, and may have something regarding a connection to Botts in Virginia.
