It is often claimed that Elizabeth was the daughter of Richard Coffin and Elizabeth Loveys. However, it appears that this couple was from a different county and their daughter Elizabeth actually married someone else.
That she was married three times and who her husbands were is documented in Hobart's Journal:
Elizabeth married first Thomas Thaxter in England. They immigrated to America, settling in Hingham.
Elizabeth married secondly William Ripley 29 Sep 1654. There were no recorded children of this union. Elizabeth would have been 54 at the time of her second marriage. Her maiden name was unknown; she was the widow Thaxter when she married in 1654 William Ripley.
Elizabeth Riply married thirdly, in Dedham, Massachusetts, (then part of Suffolk County) John Dwight of Dedham on 20 11mo. (Jan) 1657/58.
"Elizabeth Dwight, deceased ye 17 July 1660," in Dedham, Massachusetts.
