Pretty bad when even the Rom don't want to own you . . .
BTW, Blyth or Blythe is a pretty common Borders name, since it is a descriptive adjective and could have become anybody's surname. Now, if he had been a Faa, that name's uncommon enough that I'd believe there was probably a connection. There's an old ballad about "The Death of Johnny Faa" that I used to sing. He ran off with the Earl of Cassilis's lady and got hanged for it in 1624.
