The wife of John Dix was named Mary, but was her maiden name really Bidwell. The Farman source says so, but I can find no proof. Also cannot find a source that they were married in June 1676. There was a Mary Bidwell (Bidwell-100) who married John Meakins, but she cannot be the wife of John Dix as many online trees claim, because the births of the Dix and Meakins children overlap in time. Perhaps the Farman source made the same mistake. Anyway, if John Dix was married in June 1676, I assume a marriage record would show the maiden name of his wife Mary. I have had no luck finding such a marriage record.
