Sorry I haven't got back to sooner. All the info. I have on Jacob BRIGGS and decendants came from my great-grandmother Grace, and a little book she filled out for my family many years ago. She passed away last month at age 98 and it may take awhile to sort through her things to find exactly where she got her info.I assume that it came from her parents and/or grandparents (possibly even her great-grandmother Mary-Ann WILLIAMS, wife of Samuel Blakey BRIGGS, who was alive for approx. 16 years after Grace was born.) Again I am sorry it took me so long to respond. I am in college right now and studies come first.
