I don't know of a Sonny Brown. If , on the other hand, it is one of Sidney Brown's, he was one of the first Cajuns to start building accordions in Louisiana.

I have to echo the comments made by blue norther steve; it is really a treat to roam your web site. I found it particularly enjoyable to view the old acadian wood home built in the 1830's. I have friends in Breaux Bridge that live in a very similar home.
