Major DNA Discoveries

March 2023: New Y-37 results from a descendant of John SAINSBURY (bap 1778, West Lavington) confirm our August, 2022 hypothesis that Joseph SAINSBURY of Devizes, husband of Mary Ann NORTH, was not the Joseph baptised in Market Lavington, Wiltshire on 12 Sep 1790 (son of John SAINSBURY and Grace Smith HOBBS). We are confident this Joseph was baptised in 1787 and was the younger brother of John SAINSBURY (bap 1778, West Lavington). Joseph and John were sons of James SAINSBURY and Mary NORRIS. Additional DNA and documentary evidence tend to refute the theory that this line descends from John SAINSBURY the younger of Urchfont (1664-1719). (See August 2022, below). John and Joseph's father was James SAINSBURY, baptised 1747 in West Lavington, the son of James and Elizabeth SAINSBURY. However, that James's identity is unclear because there is only one 1720s James SAINSBURY baptism in West Lavington, but there are two James SAINSBURY marriages in that parish: 1742 to Mary SAINSBURY and 1743 to Elizabeth LEMON. So it's possible the James SAINSBURY who was baptised in 1723 married Mary SAINSBURY (when he was still a minor); the identity of the James SAINSBURYs who married Mary SAINSBURY and Elizabeth LEMON needs to be confirmed.

February 2023: Family Tree DNA rolled out a great new tool for surname projects like ours. It's called "Group Tree" and it shows how various branches of Sainsbury-Sansbury families, and others with matching Y-DNA patterns, are related on patrilineal lines. With this tool, we can now see that the most recent common patrilineal ancestor of all Sainsbury/Sansbury families in our project with members who've tested at the Big Y-700 level was a Stone Age man who lived around 47,000 year ago(!) Here's a link to our Sainsbury-Sansbury Big Y-700 Group Tree. You can select and de-select groups to see relationships among group members with Big Y-700 tests:https://discover.familytreedna.com/groups/sainsbury-sansbury/tree?subgroups=176838,266399,272624,299270

August 2022: Results from a new Y-DNA test indicate Joseph SAINSBURY of Devizes, husband of Mary Ann NORTH, was not the Joseph baptised in Market Lavington, Wiltshire on 12 Sep 1790 (son of John SAINSBURY and Grace Smith HOBBS). This is a significant discovery because more than 100 public family trees on Ancestry indicate he was their son. Based on this new Y-DNA evidence, we believe Joseph may descend from John SAINSBURY the younger of Urchfont (1664-1719).

July 2022: Family Tree DNA’s new DISCOVER tool indicates most members of our group (i.e., those who belong to Y-DNA Haplogroup I-Y42503) descend from a man estimated to have been born around 500 years ago. This would place their common ancestor in a timeframe that includes John SAINSBURY, rector of Ewelme, Oxfordshire (d. 1464) and the John SAINSBURY who lived in Easterton, Wiltshire in 1507 (and likely had a son, John, b. c1507).

January 2022: Big Y-700 testing indicates the SANSBURY family of the southern US, the SAINSBURY family of north Somerset (UK) and one SAINSBURY line of Urchfont (UK) descend from John SAINSBURY the younger of Urchfont (1664-1719); additional evidence indicates John SAINSBURY the younger was not the biological son of his documented father.

July 2021: Big Y-700 testing has further refined the I-M170 haplogroup of SAINSBURYs and SANSBURYs to Y-DNA haplogroup I-L38.

June 2021: We found DNA evidence that links a large SAINSBURY/SANSBURY family from Portsea, Hampshire with an 18th-century SAINSBURY family in Westbury, Wiltshire and a SANSBURY family from colonial Prince George's County, Maryland.

March 2021: We identified a new genetic cluster (Y-DNA Haplogroup I-M170) that includes two 18th-century SAINSBURY families in England and a SANSBURY family from Prince George's County, Maryland.

December 2020: We found a surprisingly close genetic connection at the Y-67 level between a tester of Basque origin and the SAINSBURY-SANSBURY families of north Somerset and South Carolina; Big Y-700 testing later indicated this was a more distant match than the Y-67 numbers suggested. But it does connect those families with a tester in the apparent place of origin of this haplogroup just prior to their arrival in England, perhaps about 2,000 years ago.

March 2019: We discovered a genetic connection (Y-DNA Haplogroup R-M269) between the 18th-century SAINSBURY family of north Somerset, England and the 18th-century SANSBURY family from Cheraws District (later Darlington County), South Carolina.
