They were the parents of Ebenezer who married Lydia Ellis. Unfortunately I have misplaced the photocopies I made of the book, Swains of Nantucket, Tales and Trails, but go the basic information in a different manner. I will have to go up to Slake to rephotocopy. Their son Ebenezer and Lydia Ellis had the following children- Ebenezer ( Jan 11 1772), Lydia (April 26 1774- 1812), Moses ( April 18 1776), Shubael( Feb 1778- Jan 10, 1808), Phebe(June 5, 1782-died 9 Oct 1849) and Valentine( 5 Oct 1782-Jan 10-1808). It is Shubael and Valentine who are reported as having "died at sea" in 1808. Their Shubael married Sally of New York. My Shubael married Sarah Turner but died in 1849. I have looked at all of the Shubael Swains that I can find and this is the only family he fits, as his year of birth is around 1777, and theirs was born 1778. Mine died Sept 20 1849 at age 72. So many things fit except this died at sea problem. Sue
