I have a family history sheet from the Preston Library on the Mason Family, type written with several sources, one being the Morton History (however, my line of the Mason I know is mixed up so not everything written is correct) It looks like your Charlotte is part of my line -- her brother William is my 2 ggf. Sarah CASEY is the daughter of Nicholas Casey who faught in the Revolutionary War from Hampshire, VA (now WV) I will attach the listing I have of this family. And will be glad to share what I have.
