My Perry family history, researched and written in the 1930s by Charles M. Perry, includes the following about the Seaver family. Hope it fills in some missing info and helps someone - I welcome any corrections or additional information:
"Robet1 Seaver emigrated from London in 1634 in the ship "Mary & John". He settled in Roxbury. He married Dec 10, 1635 Elizabeth Ballard (or Bullard). She came in the same ship or shortly before. He owned land adjoining Griffin Crafts. His wife Elizabeth died June 6, 1657 and he married again. He died May 13, 1683 aged 74 years. Children were all by his first wife.
Elizabeth2 Seaver was the 3rd child of Robert and was baptized Nov 19, 1643. She married Lieut. Samuel2 Crafts Oct 16, 1661.
