Isaac Allerton

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.

Based on a deposition given in 1639, Allerton was born in 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.

The apprentice record as translated from Latin (Isack Allerton fil Bartholomei Allerton..): '21 June 1609, Isack Allerton, son of Bartholomew Allerton late of Ipswich, county Suffolk, tailor has bound himself apprentice by indenture to James Gly, Citizen and Black Smith of London for seven years from the Feast of the Nativity of St. John the Baptist last.'

In Leiden in 1611, Allerton stated he was from London but the actual place of his birth is unknown.

Also living in Leiden in 1611 was Allerton's sister Sarah (Allerton) Vincent, widow prior to 1611 of John Vincent. Isaac and his wife, Mary, and Sarah and her second husband Degory Priest, had a double wedding in Leiden on November 4, 1611. In the records of the time, Sarah is noted to have been "of London". Also in Leiden at this time was John Allerton, who may well have been a relative of Isaac's or Isaac's brother, but this has never been proven for certain.
