Genealogy / Mikilewicz - Birth certificate for great grandfather [4]

Hello,
So I know its terribly hard trying to fins information from Poland pre 1900s but I'm really interested in my family history and am trying to find information on my great grandfather's parents. His name is Bronislaw Mikilewicz born 1895 in Wilna, Poland.

I've read that birth certificates are really hard to get a hold of in Poland so is there any other way I could obtain some information? I don't think we have copies of his death certificate so I can't ring up the consulate either.

Any advice would be greatly appreciated!!

Thank you.
