William Dominni and "distinct yDNA"

[John Bruce Douglas]

Can anyone tell me the significance of a distinct yDNA? I'm a descendent of William Domini, (please see below).

"William Domini has emerged as a distinct yDNA line in the Douglas family. Domini was thought to be an illegitimate son of George (13th or 15th Earl of Morton), and half brother of James (14th or 16th Earl). However his DNA type does NOT match James’s son John. This has been proven by testing two men who are descended from John (5th cousins once removed), and finding that they match. This proves John’s genetic type. Similarly 2 descendants of Domini have proven his haplogroup."

"So we can say with confidence now that either Domini or James or John is not descended genetically from George. And since Domini’s genetic type is distinctively Irish (and his mother was Irish) it is likely that Domini has an Irish male ancestor, possibly his father.

""Dominie Douglas was born at or near Belfast in Ireland, 2 May 1732. His parents were of Scotch decent and undoubtedly belonged to higher class of society as Dominie well remembered that his father was a man of some distinction; had horses and servants and kept up an expensive establishment. But both his parents died when Dominie was only six or seven years old leaving him to care of an elder brother who was then an adult, who for motives unknown whether good or bad cannot now be known , placed Dominie board a merchant vessel when he was about eight years old, providing him extremely well with clothing suitable for a gentleman's child."

With no identifiable ties/relatives to Ireland or Scotland, and William Domini being sent to America as a child, would this distinct yDNA be distinctly American?

John,  This might be worth posting on the DouglasDNA forum where you will get some expert advice on DNA.
