Random quote: "Kein größerer Schaden kann einer Nation zugefügt werden, als wenn man ihr den Nationalcharakter, die Eigenheit ihres Geistes und ihrer Sprache nimmt." Immanuel Kant - (Added by: Tomas Baranauskas)
"Where I live in north Italy near Venice there are a few small towns whose names (Sarmego, Sarmeola,...) some say come from "Sarmatian" due to settlements the romans organized in those areas that had de-populated"
So perhaps the Minghella family are descendants of a Sarmatian prefect.
The Notitia Dignitatum site has sheilds also and from what I can make out there were Alans also.
I am going to try to obtain the book about the Alans in the West as I am interested in the Alan/Breton connection.
