I recently began trying to assist my sister with her research on our Briggs line- in other words, I'm a novice and none of the following is verified!
Clement Briggs, born 1587/1598 was living in Southwark, Surrey, England in 1616. At some point between 1616 and 1648 he immigrated to the U.S.. He married twice, to Elizabeth born about 1618 of Weymough, Suffolk, MA, died 11 Aug 1691 and buried in Weymouth, Suffolk, MA., and to Joan (or Jeanne)Allen sometime before Mar 1630 in Dorchester, Norfolk, MA., Joan was born 1592/1602 of Weymouth, Dorset, England and died 1638/1639 of Weymouth, Norfolk/Suffolk, MA..
You probably already have all this info, which I got from familysearch.org., but sending anyway. If you have any info regarding children born of Elizabeth and Clement I would be interested since I've not found any. His children with Joan Allen are shown as Thomas, B-14 Jun 1633 Weymouth, Norfolk, MA, D-1 Apr 1696 Tunton North Pur, Bristol, MA.; Joanna, B-1635 Taunton, Bristol, MA. D-1685 Portsmouth, Newport County, Rhode Island.; Jonathon, B-14 Jun 1635 Weymouth,Suffolk, MA. D-18 Nov 1690 Taunton, Bristol, MA.; John B-1637 Weymouth, Suffolk, MA. D-before 1662.
I have additional info on the children of Thomas Briggs, but Clement either had brother(s)or children that came over with him. There is mention of aJohn Briggs B-1614 in England D-about 1686 Taunton, Bristol, MA.. Possibly a child, Richard B-1640 Taunton, Bristol, MA.D-13 Dec 1692 Taunton, Bristol, MA. Richard possibly had a son named John B- 13 Feb 1672 Taunton, Bristol, MA.D-29 Jun 1750 Norton, Bristol, MA. One of his Children, Azariah had a son Azariah who had a son named Zephaniah and if this ever checks out, this Zephaniah is sort of a problem for me. One of his children was named Zephaniah, but was supposedly born in 1835 after his father had died about 1829. The child Zephaniah had a son named Zephiniah, who was the father of Zeph Briggs, my great grandfather.
