 He immigrated to America either with or shortly after William Pynchon, between 1630 and 1635, and became a full member of John Eliot's congregation at Roxbury (later incorporated into the city of Boston).The Chapins lived in Roxbury till the close of the year 1642, as on 15 of October of that year Japhet was baptized there.Soon after this, however, they must have moved to Springfield, for we find them there in January 1642/3.
