William:Do you have any Francis BRIGGS in your family?He was b. 1755 (I believe in RI) and at least in 1799 m. to Zerviah CHURCH.I can't find her parents (for positive)....she might have changed her name due to religious reasons, etc.HE could have have a prior m. to Marbury JONES in East Greenwich, RI.
If any of this has any meaning, please contact me. Thanks much. Barb (BRIGGS) Byington at firstname.lastname@example.org
