As of November 21, 2020:
- Low Priority as no known Y-DNA descendants of Isaac Allerton. See Possible Y-DNA Descendants below. In addition, research on the family of Bartholomew Allerton (who moved to England) is needed.
For more information see: Wakefield, Robert S. and Margaret Harris Stover, Mayflower Families Through Five Generations, vol. 17 Allerton
Isaac Allerton was born about 1586, son of Bartolomew and Mary (_____) Allerton of East Bergholt, Suffolk, England. He died at New Haven (now part of Connecticut) between 1 Feb 1658/9 - 12 Feb 1658/9. He was married three times: First at Leiden 4 Nov 1611 [NS] (see Media:NL-LdnRAL_AR_1004_198_007.jpg.jpg for electronic scan of Leiden record. See also typed transcript of record.) to Mary Norris who died at Plymouth on 25 Feb 1620/1. Isaac married second, New Plimouth between 1623 - 1626 Fear Brewster. Isaac married third bet. 1635-1644 Joanna Swinnerton (no children).
By his first wife, Isaac had: Bartholomew (c1612), Remember (c1615), Mary (c1617), infant child (bur. 5 Feb 1620), and stillborn son (Dec 1620). By his second wife, Isaac had Sarah (c1626, apparently d.y.) and Isaac (c1628).
Bartholomew "Bartle" Allerton was born in Leiden about 1612. and died in Barnfield, Suffolk, England between 15 Oct 1658 - 19 Feb 1658/9. He is believed to have married twice: fist by 1640 to Margaret (____) who pre-deceased him, and second Sarah Fairfax. Bartholomew had four children (order uncertain, all born after 1640): Isaac, Mary, Dorothy and John.
(Col.) Isaac Allerton (II) was born in New Plimoth about 1630 and died sometime between writing his will (Westmoreland Co., VA 25 Oct 1702) and the will being proved (30 Dec 1702). Isaac was married twice: First prob. in New Haven, CT about 1652 to Elizabeth (_____) and second, in Virginia between 8 Sep 1662 - 30 Jan 1663/4 to Elizabeth Willoughby, widow of both Simon Overzee and George Colclough. By his first wife he had Elizabeth and Isaac. By his second wife he had Willoughby, Frances and Sarah.
Possibly Isaac Allerton was born New Haven, Ct 11 Jun 1655. He was not mentioned in the 1702 will of his father. These are the only undisputed facts about Isaac (III). There was an Isaac Allerton in New Haven who is said to have had the following children (by wife/wives unknown): John (c1685 m. Elizabeth _____), Jesse (c1687), poss. Thomas (likely d.sp.) and Isaac (c1696 died young). There is much uncertainty about this line but it is known there were Allerton families in Connecticut, New York and Rhode Island who all believe they connect back to the Mayflower passenger Isaac Allerton through Isaac3.
Willoughby Allerton was born Cople, Westmoreland, VA about 1664 and died there between his will: 16-17 Jan 1723/4 with it being initially presented to court 26 Feb 1723[/4} and probated 25 Mar 1724. He married three times, first bef. 1700 Rosamund Fitzhugh (believed to have died s.p.), then about 1702 Sarah Tavener and lastly, abt 1720 Hannah KEENE, widow of John Bushrod. and they had two children: Isaac (1702) and Elizabeth (1708). This son Isaac died in 1739 and while he had three sons (Gawin/Gowen, Isaac and Willoughby) they all died s.p. by 1759.

- Based on the assumption he was their first child.
- MD 40:7-10
- Still need to discover by which wife
- MD 40:8-9 from Probate records of the Archdeaconry of Suffolk, 1644-1700, W109/92, R73/208
- Not named in the 1627 Cattle Division. His father was in England until late Spring 1627. As such, the son could not have been born until ca Mar 1628 at the very earliest. He received a land patent in Virginia on 21 Sep 1652, so he must have been at least aged 21 at that time, so he was born before 21 Sep 1631. In addition he graduated from Harvard University in 1650. See Lambert, Barbara Merrick, "Important Allerton/Brewster Connections", Mayflower Descendant 42:117-23.
- Some claim Col. Isaac and Elizabeth had another daughter, Mary, who married about 1685 John Newton and had at least three children. However, Mary was not named in her father's will and the GSMD currently does not accept lines of descent from her. See WikiTree for more information.
- After Willoughby's death, widow Hannah married aft Mar 1724 John Cooper.
Possible Y-DNA descendants
An Isaac Allerton with wife Elizabeth was living in the New Haven, Connecticut area in the latter part of the Seventeenth Century. They had sons John and Jesse. The identity of this Isaac is still unknown, but is likely either Isaac3 son of Isaac2 or Isaac3 son of Bartholomew2.
- This Isaac, who would have been the eldest son, was not named in his father's 1702 will. It is generally assumed he was then deceased, and had no surviving children. However, this would leave open the question of who was the Isaac Allerton living in New Haven (where his parents lived before emigrating to Virginia).
DNA Results TBD
Currently, Family Tree DNA does not have an Allerton surname DNA Project, but has eight kits associated with the Allerton surname.
Next Generation Sequence/Whole Genome Sequence testing
NGS/WGS testing of Allerton descendants would further refine the haplogroup assignment for this family.
