William Peck was the son of William Peck (1575 - 1604). He was born in 1604 in London, England. He married Elizabeth (1608-1683) from London. He came from England to Boston in 1637 with Thomas Yale, David Atwater, John Cooper and others aboard the Hector and arrived in Boston in 1637. He then went to New Haven in 1638 as a founder, along with his brother Henry. The Early List of Estates published by the New Haven Church in 1640 lists William Peck with four people in his household with an estate valued at 12 pds.
William was involved in a number of estates: he witnessed the will of Thomas Lamson with Nicholas Auger on Mar. 1, 1663/64, the will of Henry Peck with John Moses and Samuel Whitehead on Aug. 30, 1651, the will of William Potter with Richard Miles, the will of John Parmely with Henry Linden on Nov. 8, 1658, the will of John Thomas, Sr., on Jan. 4, 1669 with Roger Alling. In addition he took the inventory of the estate of Henry Lindon with John Nash and James Bishop on Feb, 1660 and to distribute the estate of Robert Preston in 1650 with Andrew Low. He is listed as a Proprietor of New Haven, CT, in the Year 1685 (NEGHSR, vol. 1, pp. 157–8). His brother, Joseph, also immigrated and came to Milford, CT – see below.
