Hello fellow relatives of William Erskine Marrs,
I took a free automsomal DNA (atDNA) test and had my haplogroup analyzed by Chris Morley's Y-SNP Subclade predictor, a free online too for deriving haplogroup information from autosomal results.
My paternal (Y) haplogroup is R-DF41 (R1b1a1a2a1a2c1a1d) which is linked to Clan Erskine ancestry via a Family Tree DNA research project.

This is stellar news for us descendants of William who trace him, through several sources, back to his father, John Erskine, the 23rd Earl of Mar who lead the Jacobite Rising of 1715. This is largely because I am a direct male descendant of William Erskine Marrs and thus John Erskine, which means I inherit these markers through them virtually unchanged over the generations.
I have a tree on Geni and elsewhere which indicates as much, but for convenience, I am
Zachary Adam Marrs (Erskine)
son of Anthony Jay Marrs
son of Sylvan Leon Marrs
son of Oda Herbert Marrs
son of William Henry Marrs
son of James Marrs
son of William B Marrs
son of Samuel Wayne Marrs, Sr.
son of William Erskine Marrs
son of John Erskine, 23rd Earl of Mar
To further make the case, here are some of my sources of information on William Erskine Marrs.

The dominate religionist had passed his sentence, which was that he be tied to the tail of a wild colt and it be turned loose in the streets of Edinburgh.To avoid this fearful fate, he fled his country & left friends & property behind. Originally, the name was spelled Marr, but he to avoid detection added an S since which time it has been written Marrs.
