German soldier research in Brittany

[French One]

Hello,

I'm looking for informations on a German soldier who requisitioned a room in my grandparents'house in 1944.
He worked as an interpreter in the wehrmacht.
Could it belong to the 353 ID (or the 343 ID)?
This happened in the town of Landivisiau, 35km from Brest (Brittany).
His name was GANTZ and he was ... Jewish!

Where can I find lists of names of German soldiers stationed in Landivisiau?
Thanks for your help.
Regards,

JM

Ludwig GANTZ, forced into the army, Jewish by his mother...

I've found a picture. We can see him but after the WW2.
But nothing else...
