"A grant of arms was made August 16, 1632 to Asshton of Shepley co. Lancaster....who must be accounted the ancestor of the Asshetons of Pennsylvania."
It also notes he was a kinsman of William Penn.
Seems like finding who the recipient of the arms was will be the identity of the father of Robert Assheton.
Hmm closer to me in relation thru this branch Ens. Constant Southworth
Will look at that later..
thanks Happy holidays cuz pamela.
