you might also want to post your questions on the following board - especially regarding the the community of Donner. I am a Knobloch from Lafourche parish and have a great uncle Robert, but it is not the same as the one you're looking for...don't give up - there are lots of us around here! http://genconnect.rootsweb.com/gc/USA/La/Acadian-Cajun
Good luck. Lori
