Some last minute information regarding Andre Chochon, from the 1966
edition of Benezit:

Andre Eugene Louis Chochon was born in Rennes and studied with Collet,
Ransin, and Simon.  He showed a "Parisian Landscape" at the Salon des
Artistes Francais in 1933.

Little enough, I know.

As regards valuation of the individual works you own, you may wish to
read the answer Larre-ga gave to the following question:

I hope this is helpful.  I'm sorry we collectively weren't able to
offer more information, but there is little information on-line and
offline research is terribly time consuming.  I tracked this down for
you while using Benezit to find information regarding another
question.
