Sorry it's taken me so long to reply to your posting!
I don't have a single BUSH name listed in my (large data base).I have not seen any reference to Mary Abigail SWINT being married more than once.I feel certain that she was not in Laurens County, SC in 1790.She married William Isaac PAYNE (from England) circa 1784-85, probably in Washington Co, GA.I don't believe my John SWINT could be the one who claimed land patented to John BUSH in that same area in about 1779, either.I've not seen any reference to the BUSH name in my SWINT family at all.
My John SWINT's family came from Germany.
Here is the information I have about my John SWINT's sister Mary Abigail:
