Yost Family Genealogy Forum
I have an Abraham Yost in my line, but he was born in 1751, which sort of precludes fathering Rachel. My line goes:
Nicholas Yost -> Abraham Yost -> Jacob Yost -> Charles Kauffman Yost -> John Fife Yost. Nicholas Yost evidently had at least three brothers. The only one I've been able to identify is Jacob Yost, b. 1710. They supposedly were sent to England as children to escape the Palantine wars, came to north America in the 1720s. I have no information on this Jacob's descendants, or the names of the other two brothers, who came separately.
