I’ve learned some things from working on the project, https://www.geni.com/projects/Settlers-at-Weymouth-Massachusetts-Ba...
Most relevant: the Gorges ship bringing settlers to Weymouth arrived in September 1623. Records were probably kept of the settlement by Rev. William Blackstone but were mostly lost in King Philip’s War (1676). However there is a record of Stephen Harding, Sr. - and he was born at Denbury in Devon, according to Banks:

That makes the Northampton a bit iffy, and the John b 1620 iffy as well. Stephen’s father came with wife and one infant son.
There very well might have been a relationship with Sir Ferdinando Gorges family, which was the Devon Branch. Robert Gorges brought “kinsmen, mechanics, Farmers, and Church of England ministers” (much to the horror of the Plimoth Colony).

But this Harding family (of Devon & perhaps Northamptonshire) was “not” the Harding family of Surrey associated with “a different” branch of the Gorges family.
Here’s Mary Harding, Lady Gorges
