I only have one, Scotland. (Tho his wife, Susannah Johnson might be from Scotland - can't find anything on her!)
Joseph Rainey Robertson, b. "1760-1780 in Scotland", tho, from the date he married Susannah Johnson, 24 N0v 1795, in Madison Co, KY. I would suspect him born 1775 =/- 3 years . That could make her an immigrant, Native American Indian or born somewhere in the area.
I don't know.
I have some possible places,:
>>Hamilton, Lanark, 1774 of James B. Robertson and Violet Hamilton;
>>Rhynie and Essie, 1776 , of of Joseph M. and Agnes Pirie;
Being long before the census' began, it is hard to find any confirmation or denial for these.
I have no idea when where how, or why Joseph left Scotland, nor where, when, or how he arrived in the USA, and Kentucky.
