Glenn's surname comes via Scandinavian mythology. In its modern form I think of it as German. (Think of the word 'freiheit' meaning freedom).

You will note that Freyr 'bestows peace and pleasure on mortals'. :headbang:
His ancestry on his mother's side is Irish. He refers to the Nortons & the Deans in the Dublin DVD as being family names.
The problem we have is that we don't know whether Frey is his birth surname because his mother remarried when he was very young.
I believe that he has Scottish blood too, because there was an anecdote told some years ago about him doing some family history research in Scotland.
Once again, like him my own heritage is primarily Irish (father) & German (mother) with some English & Scottish (mother).
