I am not sure about whether John Bruffey was Irish or Scoth-Irish. I do know he was born in Tyrone, Ireland in 1752 and came to America as a young man where he fought in the American Revolution.
He married a Scoth girl who was orphaned at the age of 11 and brought to America by relatives of the same name.
Now, my question is that Scotch and Irish people were not really on good terms. It was not common for Irish and Scotch to marry. Simply because the Irish were Catholic and the Scotch or Scotch-Irish were Presbyterian.
So, John Bruffey might have been Scotch-Irish or simply a converted Presbyterian.
