'TYLER, Job (1619-1700) & Mary [HORTON]? (1620?-) [wid]?; ca 1640; Andover/Mendon/etc.'
The Ancestral File gives a date of 20 Mar 1638. This date is suspicious, as the first record of Job in New England is a list of inhabitants admitted to Newport, R. I. since "the 20th of the 3rd 1638". The date was probably originally noted in someone's records as "after 20 Mar 1638" and the "after" was dropped when the information was transferred to the Ancestral File.
