I can't speak to the marriage of Susan Hambleton to Richard Ferris, but I can, with authority of due diligence and research, speak to the myth that Richard Ferris was son of Nicholas Ferrar and changed his name to Ferris.
I suspect chicanery and a genealogical crime on the part of someone, not you, who was seeking to connect the Ferris line to auspicious beginnings (like the Virginia Company) and took advantage of the fact that this black sheep of the Ferrar family seemed to have disappeared from history.
And Here:http://archive.org/stream/cu31924101858441/cu31924101858441_djvu.txthttp://archive.org/stream/cu31924101858441/cu31924101858441_djvu.txtpage 49 (Chapter III)"The nature of the family trouble which brought Nicholas Ferrar home in such haste does not appear. It may probably have been connected with the afeirs of his eldest brother Richard, who seems to have been, through life, a constant source of anxiety. John Ferrar passes over his brother's misdeeds in kindly silence; but in his father's will, made in 1620, the administration of the family property is left to John and Nicholas, Richard having his debts forgiven and receiving a younger son's portion, which he apparently squandered, for Mrs. Ferrar in her will,'- dated March, 1628, desires that, "if he deserved,"
' Both wills are given in Mr. Mayor's appendix to "Two Lives of Ferrar. "
So you see this Richard Ferrar Ferris affair is simply a manufactured myth by some Ferris family member who apparently seeks to glorify their line by linking it to Nicholas Ferrar.
And by the way Nicholas Ferrar is not my line either.
The above establishes that Richard Farrar was a Merhcant of London. The papers of George Washington have invoices to pay Richard Farrar and Company of London for diverse goods like Silverware, Fine china, textiles.
This of course would not be the same Richard Farrar son of Nicholas Ferrar, but it could be the company that he founded.
