It's hard to tell with these Yosts.There were so many of them who settled in Ohio.Some were from Switzerland (sp?).
Found a little squib about a Peter Yost b. Ohio Co., W.VA. in 1796 and came with his father to Belmont Co. when there were few settlers.(Of course, year was not mentioned.) He raised a family who are all grown men and women.(Again, no mention of children's names.) I found this in Belmont & Jefferson Cos., OH. by J.A. Caldwell.
Guess I have to write to the Belmont Gene. Soc. to find out what they have.
