From a post-it note at Rootsweb's Worldconnect:
An article which appeared in Vol. 52, pp. 18-20 of The American Genealogist, titled "Mary Andrew, wife of Henry Sweet" by Harriet Woodbury Hodge put to rest the myth that her last name was Griffen. It was believed she was because they named a child Griffen, however the author sites several deeds which clarify the relationship. She was the daughter of John Andrew and his first wife who remains as an Unknown. The kinship is clarified by North Kingstown deed 2:2ll F: On 10 June 1713 when Henry Sweet, wife Mary with William Andrews and wife Ann and Mary (Ridgely) Andrews, widow, conveyed to William Spencer land formerly of John Andrews who died intestate in Newport, "we being his said heirs."
See a text of this deed in RI Genealogical Register Vol 11 p 342 on Family Tree Maker CD.
