Kwast born in Moszczanka and Ritschke born in Ozierce - ancestors from Poland

Hello, my name is Fernanda, I'm brasilian.
I'm seaching for the history of my ancestors.
I know that my great grandfather Emanuel Kwast was born in Moszczanka in 1898 and my great grandmother Julianne Ritschke in 1895 in Ozierce (near Rozyszcze and Kniahiniek). They came to Brazil in 1935. I found documents that look like a marriage certificate, in polnish language, but its their parents marriege certificate and those documents are from Rozyszcze. I'm seaching for records of their marriage, but I don't know the date or place. I believe it took place at this Wolhynia region arround 1918. Can anyone help me? Thank you veru much in advance! If it is easier, I can also writte in german.

Best regards from Brazil!

Dear Fernanda. You don't know the place that your grandfather Emanuel Kwast and great grandmother Julianne Ritschke's marriage, right?
Then it's kind of difficult to find it, The time is too early to retrack it. BTW, Wish you can find it!
