Linda, I may have corresponded w/you before re: Vance.
Have you checked the Chickasaw I.T. marriage records for Myrtle and Baysinger?Perhaps the I.T. license is in Carter Co. Courthouse at Ardmore. Of course,there is a possibility the name is recorded with different spellings.
I found some "Bassingers" bur in Cemetery # 22 in Love County---which is southern OK.Could they have been related?Might look in that county also for a M/L.E-mail me if you'd like. winnie vance yandell
