Apparently Edward married Amey Bull & Abigail Davis; some genealogies say it is not clear which one was the mother of Edward II. But, see marriage story below. Edward was Attorney General of RI from 1677 to 1680; he was General Solicitor (same job, different title) in 1667, 1669/70, 1672, and 1677. He was Deputy to the RI General Court in 1678/9 and 1686, and was also a captain and lieutenant at Newport. He was probably a son of John "Webb" Richmond b.1592 & Elizabeth Nicholas, who came to America in 1635.
In 1656, Edward's Richmond's attorneys unsuccessfully sued Richard Ussell, who was Abigail's legal husband, she having been forced to marry him when Edward was already "espoused to" her. Later they successfully argued the case on the basis of trespass for breach of covenant. A petition in Abigail's name was presented to the General Assembly resulting in a declaration that the prior marriage to Ussell was "an unlawful marriage." Edward and Abigail had to pay a fine of forty shillings for living together and conceiving a child. The Court of Trials married the couple "for preventing of the like Temptation." (from "the Transatlantic Constitution" by Mary Sarah Bilder)
The following is from Daniel P. Himes' genealogy at Geni.com: "Abigail Davis, the first wife of Edward Richmond . . went to court in 1657 to annul her forced marriage to Richard Ussell. The court committee, headed by Roger Williams, finally decided in her favor, but only after delaying the decision for six weeks . . . The following summer (1658) Abigail and Edward were charged with living together contrary by law, and having a child (Abigail, born 1656) out of wedlock. They were fined and then conveniently declared to be married by the court 'as they been twice published according to law but . . . (Rev.) Obediah Holmes forbade it.' "
