Your entry on '
Alan' says that the name came to England with Bretons who followed
William of Normandy, but is uncertain about what the name means in Breton. I think it's possible that the name is not originally Breton, but is a reference to the Sarmatian (Iranian) tribe known as the Alans, who lived for a time in Gaul, based in Orleans. Most of them moved south, to Spain and into
Africa, but surely some stayed behind. I can easily imagine an
Alan reaching
Brittany from Orleans and the locals, finding his Sarmatian name unpronounceable, calling him '
Alan'. I've found references in a few online works that say flat out that the Sarmatian Alans are the source of the name '
Alan' in Western Europe. The Alans were nomads who rode horses and introduced the idea of hunting on horseback assisted by pack of dogs to Europe. There's a breed of dogs in
France and Spain that's still known as the Alano breed today.
Is there any evidence one way or the other on this idea?
Thanks!
