Very interesting thread.

I think it must have been written by an Irish traveller.

I think the daughter was saying,

Don't call him a gypsy father, he was born of this earth, and everywhere he steps he becomes the prince of the earth. He is welcomed with wine and song in mansions finer than your own.

To me it fits with the travellers philosophy and maybe even their history of metal workers in the castles of ancient kings. Of course a father would not want his daughter to run off with a landless, musician but she says he is lord of all.
