The TAG article cited above says, after giving John's birth, that, "his subsequent history is made somewhat ambiguous by the fact that there were at Watertown, at the same time, two men named John Chadwick, both of whom had wives named Hannah, and both of whom removed to Worcester." This is not entirely a true statement. By the time the younger John and Hannah started having children, the older John and Hannah had moved to Attleborough. So they were not in Watertown at the same time, and it is fairly easy to separate the families. Further, as discussed more fully on the page belonging to the other couple, the reason for thinking this John died in Worcester appears to be based on error reading the age on a gravestone, and the alleged death of his wife there in 1732. But the 1732 death of Hannah is actually in Attleborough, while the death of Hannah is in Worcester is in 1752 and belongs to the other family. These two mis-attributed deaths appear to be the only reason for thinking this John moved to Worcester, and they demonstrably belong to the other John. So this John probably never did end up in Worcester. As mentioned, his wife Hannah died in Attleborough in 1732, the last hint of this John, but where he may have moved after this is unknown. This other source suggests the son of this John ended up in New Jersey (big caveat: no evidence presented), maybe this John did too.
