Just ran across your query re Roby family. My records show that William Roby was a son of Thomas Roby (1501-1556) and Elizabeth Swaine (1503-1563/64.Mary Page was the wife of Samuel Roby (1659-1717). Thomas was born in England; Samuel in the US. I show Ruth Roby (b. 10-14-1678 in Haverhill MA; d. 4-19-1753 in Hampton, NH) married to John Sanborn (b. 11-6-1680; m. 12-10-1701; d. 10-30-1767 in Hampton, MA). Hope this helps you.
