Has anyone heard of Chohanna?

Hello,
I'm trying to figure out where my great grandfather was from. In early census records his birth place is listed as Russian Poland and on his WWII draft card he wrote Chohanna. Does anyone know what the region/city is called now? Thanks for any help you can provide.

it would be much easier if you post a picture of the document(s) in question
