Genealogy / Looking for my Polish family (Wieruszow area) [7]

I'm French but my great grand parents were Polish. So, I'm looking for information about them because I would like to organize a trip to Poland to discover my origins.

I only know that my great grand mother was born in 1893 in WIERUSZOW. I know her name and my great grand father's too.
Do you know if we can consult the registers dating back to that time in Poland?
Could you give me advice to get more information?
Thank you in advance for your help.
You can send me a PM if you want me to tell you their identity.
