I think it's hit a point where there is a spelling variation for sure... Don't know much at all about Mary.
I have the info on my ancestor William though. (the son of Charles and Mary)
William Harber born 20 march 1728 in Fillongley, Warwick, England
Married to Martha "Barnes" Harber. Martha is his second wife though. Sarah was his first, she has nothing to do with me.
