I've seen this record before and assumed this James was son of James & Anne (Wiggens) Sension.If it is James (husband of Anne) then he died before most of his kids were born.
James Sension & Anne Wiggens m. 4 Nov 1635
Children 1. (James B. 31 Jul 1636 d. 6 Aug 1641) wife of anne? 2. Mary B. 14 Mar 1640 3. Martha B. 7 Jan 1644 4. Samuell B. 3 Feb 1647 5. Sarah B. 21 Mar 1649 6. James B. 4 Apr 1652
Another child born in this time frame has the same Father James wife Anne (same as 1. James).I think Anne is wife of James not wife of the child.I think this is one of those grammar exercises where comas matter.
1.5? Jeremiah B. 21 Jan 1637 (although less than 1 yr from James' Baptism)
