Sarah's father was the son of William Briggs, b. Abt. 1644 and Sarah MacCumber. William's parents were John Briggs and Agnes Thayer. They with their children migrated to New England sometime around 1650 and were among the original settlers of Taunton, MA. I have posted a descendancy outline of this Briggs line in a home page under my name Robert H. Briggs on www.familytree.com
. On their menu screen look for home pages and click on that. If I can be of any other help contact me.
