Hi Tommy - cousin Larry here. Did you receive a direct reply to your post?
I recently found this info: Our William's youngest son, Moses & his wife, Nancy Henderson Perdew also moved to Illinois but sometime after January 1854 when their oldest son William was born in Washington County, Ohio. Their 2nd child, Mary was born in Marshall County, IL 10 Apr 1856; their 6th child, Asa was born in Magnolia Twp, Putnam County, IL 6 Jul 1866. Moses is buried in the Sawyer Cemetery in Putnam County.It would be great if we can determine if the Moses Ron wrote about is indeed our William's brother!
