To me, it looks like Chiurois or Chinrois. I don't know if there are actual places with those names, but that's what it looks like to me.
The end of the word kind of looks like a 'y', but if you compare it to "francois" in the entry above this one or "le Rois" on the left of the third line on the fourth entry on this page, I think the ending of the word is probably an 'is' with the old long 's'.
