Having looked into this further -- a) John Bridge's origins were unknown, and his first wife's name was never known.
b) His second wife's name was Elizabeth, not Susan.
c) There's not a hint anywhere that Jacob French's daughter, sister to Thomas French, immigrated. Thomas French's wife Susannah immigrated -- but she came married to him. Thomas French's daughter Susan immigrated -- but she came unmarried and childless, and was indentured to the Winthrop household for several years after arrival (and then vanished.)
