Joseph Peck married first, at Hingham, Norfolk, England, on 21May1617, Rebecca Clark, buried there on 24 October 1637. Evidence exists indicating that Rebecca was the sister of Mary Clark, who married Edward Gilman at Hingham on 3 June 1614. It is thought that Jane Clark, who married Robert Kirby at Hingham 25 July 1616 and Margaret Clark, who married Anthony Cooper there on 25 July 1609 were also sisters; all thought to be daughters of John Clark, who was buried at Hingham on 6 June 1615, and Elizabeth Clark, wife of John, buried there on 11April1602. Anthony Cooper, Edward Gilman, and Joseph Peck were all early settlers of Hingham, Massachusetts. The parish registers for Hingham begin in 1601, but there is a record in the Genealogical Society of Utah's International Genealogical Index of a Rebecca Clark, baptized there on 21 May 1585, the daughter of Samuel and Martha (Lincoln) Clark. The ultimate source of this record is apparently a "Peck Family Bible," no further information given. The submitter of the record is now deceased. Suspicion is aroused, however, by the fact that family bibles usually give birth, not baptismal records. Also the baptism happens to be exactly 32 years prior to the marriage.
John Clark, buried in 1615, was probably the son of Thomas Clark of Hingham, husbandman, whose 1593 will mentions a wife Elizabeth and children Valentine, Stephen, John, Elizabeth and Margaret. He was probably the grandson of Richard Clark of Hingham, whose will dated 20 August 1557 mentions a wife Margaret and children John, Thomas (relationship not specified but assumed to be son), Margery and Joan. He was probably the great grandson of Richard Clark, as Thomas Clark's will mentions a tenement which was formerly his grandfather Richard Clark's.
