Dea. John Willis - Deacon John Willis appears to be Disproved as son of Thomas Willis.

Research appears to indicate no relation of Thomas Willis as the father the of Deacon John Willis.
. “THEORY - John Willis was born in 1610 the son of Thomas Willis who was born in 1575 in Fenny Compton, Warwickshire, England. “The Ancestry of John D. Newport” on Rootsweb lists a detailed pedigree of this family from a Thomas Willis born about 1450 in Priors Marston, Warwickshire to Thomas Wyllys born about 1575 in Fenny Compton, but does NOT account for a son JOHN WILLIS.
This family is DISPROVEN as relations to the brothers in Massachusetts. It is instead the family of George Wyllys of Hartford.”
