Angi, Are you still pursuing research into the family of Isaac Briggs?And are we talking about the Isaac who was born c. 1825 in IL, the son of Elias Briggs b.c.1798?
If so, thought I would contact you with a short update; we are still working on this, but it would seem that we have found a marriage record for Elias Briggs marrying Jane/Jenny Rose in Scott Co. Indiana in 1823.
Still no definitive breakthrough on the parents of Elias, though; although there is still the distinct possibility that his father was James Briggs b.c. 1763, d. after 1850 Greenup Co. KY.
If you have anything to add or want to share any new ideas, just drop me a line. Regards, Larry D.H. Coats
PS:Refresh my memory...I don't recall exactly how you descend from Elias b. 1798.
