• Constant Southworth, the son of Edward and Alice (Carpenter) Southworth, was probably born at Leiden ca. 1614-16. for his parents married there 28 May 1613 (Leiden Records, as in MD 10:2). The same records show that Edward Southworth had a brother Thomas then living in Leiden. Edward died in Holland, and his widow Alice came to Plymouth and married Gov. William Bradford on 14 August 1623. Constant came to Plymouth in 1628, probably on the White Angel, and a contemporary account shows that the Plymouth Company paid twenty shillings for his passage and four shillings, eight pence per week for eleven weeks for his food. It is assumed that he, and his brother Thomas, who must have come over later, lived with their mother and step-father, Governor Bradford. The Southworth family was apparently of gentle birth, but claims that Edward Southworth was identical with the Edward Southworth, son of Thomas and Rosamond (Lister) Southworth, of Samlesbury Hall, Lancashire, are not adequately supported.
Constant Southworth married Elizabeth Collier, daughter of William Collier (PCR 1:68).3362, pp 355-6
