English Ancestry

Information on the Bradford Ancestry in England can be found at: Browne, William Bradford, Ancestry of the Bradfords of Austerfield..., The New England Historical and Genealogical Register 83 (1929) pp. 439 ff.

First Generation

William Bradford[1] 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 grandfather, William Bradford (I)[2] His Bradford grandparents died by 1600 and his mother died in 1597, so before he was aged ten, the future Governor was raised by an uncle, Robert Bradford.

Bradford married his first wife, Dorothy May at Amsterdam, Holland on 9 Dec 1613 (see Media:NL-LdnRAL_AR_1004_198_028.jpg.jpg, transcription of record also Media:Marriage record of William Bradford and Dorothy May.jpg). She had only one child, John (born about 1617) before her death at Plymouth Harbor in December 1620. This son (John) married Martha Bourne but they had no children. Thus, all of the descendants of Gov. Bradford are by his second wife.

Bradford married his second wife, widow Alice CARPENTER Southworth [1] at New Plimouth Colony, 14 Aug 1623. This was the fourth marriage to occur within this colony.[3] 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):

DNA Results I-FGC72882

===Previous Y-DNA testing===[4] Previous Y-STR testing through the Mayflower Society DNA Project and the Bradford surname DNA project Group 3[5] 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) furthers refine the clade and can potentially differentiate between the branches of descendants. As of Oct 7, 2022 two 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>FGC72882.

  2. ↑ William (I) was married twice. His first wife (mother of William (II) may possibly have been Alice Morton, great-aunt of George Morton.

  4. ↑ Some versions of the 23andMe test incorrectly report male Bradford descendants under Y Haplogroup I-Z58, when the correct haplogroup would be I-Z63.
  5. ↑ 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.
