Although John's wife is identified as Martha Packard in many places online I cannot find any evidence to support that assumption.
My research on the Packard family in the 17th and early 18th centuries has been extensive. The surname is relatively rare in Bristol County until the 1750s in Attleboro, and the 1780s and 1790s elsewhere in the county. Most of the earlier occurences are marriages of Bridgewater Packard sons to Bristol County women, with the couple settling in Bridgewater, or of Bridgewater Packard daughters to Bristol County men.
There are reasons to suspect that descendants of Thomas, son of the immigrants, were in Bristol County in the early 1700s, but that suspicion is as yet unproven and still needs extensive research.
