Isaac Allerton Sr. (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.[1]
