For what it is worth (don't know how accurate this is) I found this in old letters of my great-aunt Alice Flynn, who was born in Leitrim in 1872. "I am reading a history of the Irish race. So far I have got to the Militian race. My father was very proud he belonged to that race. They are black haired. Where Irish have married Danes, their hair is light colored."
