Edward Southworth
He first appears at Leiden on 13 November 1610 as a witness, described only as from England. A year later he stood for Isaac Allerton at his betrothal to Mary Norris, and in 1613 he did the same office for Samuel Fuller, who was marrying Agnes Carpenter. At that betrothal one of the witnesses for the bride was her sister Alice.
On 4 May 1613 he registered his own. The Leiden clerk wrote him down as Eduwaert Sodtwaert, born in England, a bachelor, by trade a saeijwercker, which is a say weaver: say was the light worsted that went into bedding and table linen. He was assisted by Tomas Sodtwaert, entered as his brother, by S. Fuller, entered as his brother in law, and by Rogier Wilson, an acquaintance. The bride was Els Carpenter, born in England, a maid, assisted by Anna Ras and Elizabeth Gennings. They were married on 28 May. Two sons followed at Leiden, Constant and Thomas.
He did not sail in 1620 and neither did his wife. The last document that has him alive is a letter Robert Cushman wrote from Dartmouth on 17 August 1620, while the Speedwell was being trimmed and already failing, and addressed to his loving friend Ed. S. at Heneage House in the Duke Place, London. In it Cushman wrote that an infirmity of the body had seized him which would not leave him till death, and he did not know what to call it, but it was a bundle of lead, as it were crushing his heart.
Edward Southworth was dead by about 1621. His widow came out in the Anne in 1623 and married the governor of the colony within a few weeks of landing, and his two boys followed in 1628.
His parentage is not established, and two English families have been proposed for him.
