We have added a new volume to the searchable database of authenticated Mayflower Pilgrim genealogies, Mayflower Families Fifth Generation Descendants, 1700-1880:

  • Allerton, Isaac (Vol. 17)

This update adds 191 pages with 3,300 supporting records and 10,300 searchable names related to the descendants of Isaac Allerton.

This database is being constructed from the General Society of Mayflower Descendants (GSMD) very well-known series of books Mayflower Families Through Five Generations: Descendants of the Pilgrims who landed at Plymouth, Mass., December 1620 which document the first generation of descendants of the Pilgrims. Through our partnership with GSMD, American Ancestors is delivering this database with a full index of the fifth-generation descendants, and their children, coupled with the page images for those people.

Isaac Allerton, born in 1586, was a merchant and a tailor. He embarked on Mayflower with his first wife Mary Norris, their 3 living children, and his apprentice, John Hooke. His sister Sarah was also a passenger, married to Degory Priest. Isaac was chosen as assistant to Governor Bradford in 1621. Members of the colony became dissatisfied with how he managed the finances of the colony, increasing debt and mixing his own business with the colony’s finances. He was eventually banished from the colony for his unscrupulous dealings, going on to live in Marblehead, New Amsterdam, and New Haven. Around 1626 he married his second wife, Fear, who was the daughter of passenger William Brewster. They had two children. He later married a third wife, Joanna Swinnerton, in New Haven, where he died in 1659. This information is also available on our Mayflower 2020 site here.

This database index includes birth, baptism, marriage, death, and deed records for these individuals, and where available, the names of parents and spouses. We thank our volunteers for all their efforts in bringing this newly searchable data to you!
