The birth date of Thomas, Jr. is not clear. Methuen Vital Records show Thomas, son of Thomas and Hannah, born January 12, 1720, and Tho., son of Tho. born January 9, 1730. The first may have died as a child, but if so, his death is not recorded in the Methuen VR's.
Thomas Jr. married his first cousin, Elizabeth Gutterson, daughter of Joseph and Sarah Richardson Gutterson, on November 28, 1754.(Methuen VR's p195)

Methuen married Samuel Hutchins, Jr. on December 13, 1739 (Haverhill
VR, V2 p267)
John, born March 28, 1724 (V1 p437).
Methuen Vital Records confirm the birth dates which Vinton gives for Hannah and Francis ((p107).
