I've tried following the Brown Co. Briggs lines a bit. If you have this information then please ignore the following. John Lenard Briggs married 3 times. 1) Mary Johnson, 2) Matilda nee Briggs, and 3) Celesta Bullard. There is another Briggs/Bullard marriage of which I'm aware. I don't recall seeing an adoption by Henry, but perhaps that is the case as Henry b. 1806 wouldn't have been eligible til 1827. If 18 was a marriagble age, then Philip R. Briggs b. 1824 could be Henry's son by Sarah Johnson. That still leaves John L out in the cold, unless ... I've got Matilda as the son of Philip Briggs and Mary Elizabeth Fry.
