Status summary

As of December 7, 2020:

  • Bradford surname project contacted
  • Recruiting men whose Y-DNA ancestor is Gov. William Bradford for Next Generation Sequence/Whole Genome Sequence (NGS/WGS) testing. Interested individuals can contact Raymond Wing email: wing (DOT) genealogist (AT) gmail (DOT) net
  • One Big Y-700 test of a Y-DNA descendant of Gov. Bradford is pending. Other NGS/WGS testing would be of further assistance.

Background

Paper trail

William Bradford was baptized at Austerfield, Yorkshire, England on 19 Mar 1589/90, son of William Bradford (II) and Alice Hanson. His father, William (II), died 15 Jul 1591 and William (III) went to live with his paternal grandparents, William Bradford (I) and Alice Morton. His Bradford grandparents died by 1600 and his mother died in 1597, so before he was aged ten, the future Gov. was raised by an uncle, Robert Bradford.

Some sources list a pedigree for Gov. Bradford beyond his grandfather, William (I), but this pedigree has not been verified.

Bradford married his first wife (Dorothy May) at Amsterdam, Holland on 9 Dec 1613. She had only one child, John (born about 1618) before her death at Plymouth Harbor in December 1620. This son (John) married Martha Bourne, widow of (Lieut) Thomas Tracy. Martha had several children by Tracy, but none by her second husband. Thus, all of the descendants of Gov. Bradford are by his second wife.

Bradford married his second wife, Alice Carpenter [1] at New Plimouth Colony, 14 Aug 1623. This was the fourth marriage to occur within this colony. They had a daughter, Mercy (born before the 1627 Land Division) and two sons (who both carried on the Y-DNA of the Bradford family):

Second Generation

(Maj.) William (IV) born 17 Jun 1624. He was was married three times, first abt 1650 Alice Richards; second to an unknown woman; and third aft 1677 to Mary (At)WOOD Holmes. By his first wife he had nine children: Maj. John, William (V), Lt. Thomas, Mercy, Alice, Hannah, Melatiah, Lt. Samuel, Mary and Sarah. By his second wife he had a son, Joseph. By his third wife he had four sons: Israel, Ephraim, David & Hezekiah.

Joseph born 1630. He married Jael Hobart (daughter of Rev. Peter) at Hingham 25 May 1664. They had three sons: Joseph, Elisha & Peter.

DMA Results I-Y21372

Previous Y-DNA testing

Previous Y-STR testing through the Mayflower Society DNA Project and the Bradford surname DNA project Group 3[1] has indicated that the Bradford lineage belongs to the Y haplogroup I-M253, which is quite common in Northern Europe and Northwestern Europe. Plugging in the modal 111 STR values for the family into the Nevgen Haplogroup Predictor tool gives a prediction the family falls under: I-M253>DF29>Z63>BY151>BY351 with a 95.6% probability.

NGS/WGS testing

NGS/WGS testing of patrilineal (all male line) Bradford descendant(s) would further refine the clade as well as possibly differentiate the branches of descendants. As of May 21, 2021 one Big Y-700 test result has been posted to the Mayflower DNA Project website. The haplogroup beyond BY351 to >BY3407>CTS2910>Y10994>Y21374>Y21371>Y21370>Y21372.

  1. At the bottom of this group are individuals who are NOT descended from Gov. William Bradford and fall under a different Haplogroup of I-M253.
