Edward Jessup was born in Yorkshire, England, about 1624. He was the son of John Jessup (9th GGF - c1606) of Yorkshire, England, Wethersfield, CT, and original settler of Stamford, CT, and Joanna Kerrich (9th GGM) of Saxstead, Suffolk, England. Edward immigrated from England and settled first in Fairfield, CT, then moved on to Stamford, CT. He married his first wife, Miss Whitmore (8th GGM), and their child, Elizabeth Jessup (7th GGM), was born in 1644. The demise of his first wife is unclear, but in 1650 Thomas married his second wife, Elizabeth Bridges, and they had a daughter and a son between them.
By 1652 Edward and his family had moved to Newtown, Long Island (now Elmhurst),
