Hi Richard,
Welcome and thank you for supporting WikiTree.
As a descendant of Richard, you have quite a name!
I too appreciated the Edith Summer work on Richard York. To my knowledge tough, the notion that he arrived with Wiggin on the James is conjecture. As I recall, the record of the ships arrival was memorialized in Winthrop's journal. But for Wiggin and possibly one or two others, the names of those arriving then were not recorded.
Wiggin did settle at Dover shortly, bringing with him say thirty. It's possible Richard York came then, but his arrival in Dover by 1635 is based on his own deposition, taken later.
On 18 (8th) 1652 [18 October 1652], John Ault testified and Richard Yorke affirmed, ".. in the yere 1635, that the land about Lambreel river was bought by of the Indanes & made use of by the men of Dover & myself both for planting & fishing & feling of timber."
See John Ault and Richard York 1652 depositions, John Scales, Colonial Era History of Dover, New Hampshire (Manchester, N.H.: John B. Clarke Co., 1923), 183 (Depositions about Lampreel River); digital images, GoogleBooks.
