The crests, however, are very English.
Maybe Middleton and Bentley?:
I would think this is perhaps one of the easier ones for the right person to track down, a marriage between a Middleton and a Bentley (if indeed this is right families, as the above is only offered as a possibility) with maybe a Swiss connection?
I'll move the topic to the Family Crests section of the forum.
