I'm unable to add to your information. Perhaps you can help me by citing the source of the information. I've listed the 1st marriage of TB as you've mentioned it here. It may be in the volume Harold G. Barker, Maurine Clifford, William H. Hunt, Jr., Briggs Families of old Anson, old Rowan, and Davidson Counties, North Carolina and Brown County, Illinois,(Rye, N.Y. : H. G. Barker & M. Clifford & W.M. Hunt Jr., 1985). I've not got it in front of me. Is your information from a different source and do you have Thomas as the son of Wm A. Briggs, Sr.?
