William Fitzwater married Ann McCaslin - Virginia

Have been searching for many years for the parents of Ann.Several years previous I obtained court records in Augusta Co., VA naming John McCaslin (one as Administrator to the estate of a Fitzgerald) and Andrew McCaslin.These men may be brothers to Ann.A few months ago, I was told that John McCaslin owned land on Muddlety Peg Creek, Greenbrier Co., VA (now WV and in Nicholas Co.)and obtained the deed.His land touched Robinson and John Fitzwater (twin and son of William and Ann).This bit of documentation seems to reveal John McCaslin was most likely a "relative" possibly Uncle due to age, and possibly brother to Ann.

Does anyone have any information or documentation to shed light on this?If so, please let me know!
