As one who grew up with the Clancy Borthers version, I've always assumed, with no factual basis, that the "he is no gypsy ... but lord of these lands all over" line was not to be taken literally - but rather in the more poetic sense of "He is not a homeless scoundrel but is "king" of all his surroundings". It's interesting to read about the John Faa history which suggests that meaning may well have been intended to be literal. Fascinating and highly educational thread - thanks to all for the great research.
