About us
The Stewart-Bute DNA Project has been designed to cater for men who descend, or believe they descend, from a specific family line of the ancient Scottish family known colloquially as the Royal Stewarts. This family started out in Scotland when the first of the line, Walter Fitz Alan (1110-1177) was appointed High Steward of Scotland under King David I. His descendants became Hereditary High Stewards of Scotland, and the 4th High Steward, Alexander Stewart (1214-1283) was the first to use Stewart as his surname.
Descendants of this line of Stewarts belong to the R-M269 Y-DNA haplogroup and test positive for a specific Y-DNA signature: GATA-H4=10, 406S1=11, 565=11. They also possess particular SNPs below the L21 branch of R-M269, including L744, L745, L746 and others.
An important branch of the family are the Stewarts of Bute, who descend from the line of King Robert II of Scotland via Sir John Stewart of Bute, and are distinguished by the possession of particular SNPs below the R-L746 branch, namely FTT46, Y14197 and Y14198.

If test results do not show any of these details for the Y-signature of the Royal Stewarts or Stewarts of Bute, membership in the project will be cancelled. If there are other reasons to remain in the project that would benefit a tester's research, please explain in a response to the administrator for further consideration.
