This Welch Family genealogy starts with the marriage of James Welch, Sr. and Mercy Sabin who was a Mayflower descendant of John Billington. Also, there is a line that connects this Welch Family with another Mayflower passenger, William Bradford, through the Ripley & Manning line. Both of these connections have been verified by the Mayflower Society.
Please note that the origin of this JAMES WELCH Sr.(b: abt 1655, Swansea, Bristol Co. MA and d: bef 22 Nov 1726, Plainfield, Windham Co. CT) has not been learned. He was NOT the soldier of King Philip's war, awarded bounty land at Voluntown, CT, with a son James who lived and died at Colchester, CT. The two entirely different families with the same names have often been confused.
My research continues on this James Welch and as a direct decendant of his, I welcome any and all additional information that you may have on this family that migrated from CT to NY and PA.
