Major DNA Discoveries

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.
