AuroSprings here on BYC has Cotton Patch,We have been looking at a few like- cotton patch, embden Pilgrim, Pomeranian, and the curly ones(I don't know what they are called)
Mrs Magoo would be one of your closest sources for Pomeranian geese
as already mentioned the curlies are Sebastopols.
I would stay away from all hatcheries except Metzers for buying waterfowl.
There is a waterfowl breeders directory here on BYC as well
