Overview
Isaac Allerton (c. 1586 – 1658/9), and his family, were passengers in 1620 on the historic voyage of the ship Mayflower. Allerton was a signatory to the Mayflower Compact. In Plymouth Colony he was active in colony governmental affairs and business and later in trans-Atlantic trading. Problems with the latter regarding colony expenditures caused him to be censured by the colony government and ousted from the colony. He later became a well-to-do businessman elsewhere and in his later years resided in Connecticut.
English ancestry
Based on a deposition given in 1639, Allerton was born in Suffolk, England about 1586–88, although clues to his ancestry have long been quite elusive. Some records from colonial Dutch New Amsterdam (New York) note he was from the English county of Suffolk. Allerton's son Bartholomew did return to England from Plymouth and served as a minister in Suffolk which may indicate a connection to that county. In 1659 the will of Bartholomew was proved, and at that time he was residing in Bramfield, co. Suffolk but no other records relating to the Allertons, a quite rare name, have ever been found in Suffolk.
Author and genealogist Leslie Mahler, writing in The Mayflower Quarterly of March 2009, notes that an Isaac Allerton, who appears to be the Mayflower passenger, is mentioned in the 1609 apprenticeship registers for the Blacksmiths Company in London. This record indicates Isaac to have been the son of Bartholomew Allerton, tailor of Ipswich, Suffolk.
