Mary Catherine Vance was my 4g grandmother, she married William Cotter on 25 Jan 1784 in Rockbridge County, Virginia. I copied the marriage bond from the internet and it was signed by Patrick Vance, thought to be her uncle. John Vance is thought to be her father, but I am seeking proof of this fact. William and Catherine moved to Union District of South Carolina and lived near Robert and Mary Lusk, Mary is thought to be her aunt. Would appreciate any information about Mary Catherine Vance Cotters parents and siblings. Billie
