Major DNA Discoveries

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 indicated SANSBURY family of the southern US, 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 further refined the I-M170 haplogroup of SAINSBURYs and SANSBURYs to 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 1,000 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.
