Most accounts of the James Jackman who died 1694 in Newbury, MA, show him as being born about 1611. Consider this: Since his first child, Mary, was born in 1644, he must have been born about 1619 or earlier, since age 25 was about when most men married back then. On the IGI there is a James Jackman christened 6 Aug 1619, Hornchurch, Co Essex, Eng. Father was a Edward Jackman. I have also found information on a Edward Jackman, alderman of London, who died 1569 in Hornchurch. Maybe, just maybe, this is the same James Jackman that died in Newbury.
