Genealogy / Inscription on Headstone.. (trying to do a Family Tree) [4]

I am trying to do a Family Tree... I don't have anyone in the family to ask. Most are past away and the ones that are alive, never cared to know.

I took a picture today of my Great Grandmother's grave site and there are 2 other head stones right next to it, Thinking it was my great grandmothers parents? But I don't know what it says. I am inserting a picture.

I am assuming under the name is the town they died? I have no idea. Please don't make fun of me..lol. Is there a way to find information on ancestors from Poland? I'm assuming on the head stone that they were from wrzesnia? would that help for my search? Any information for my serach would be Greatly appreciated!!

Let me know what the headstone says under their names?
I looked on ancestors dot come web site and from what I found, their names were Nick and Pauline. but on the headstone it's Appolonia and Mikolaj. I'm confused. PLEASE HELP.

THANK YOU!!!!!

sorry I tried uploading a picture but didn't work.
