Do you know the Poznan Marriage Project? You can find it here:

When you search for Joseph Kubiatowicz as the groom, you will find the marriage you are looking for as #21/1863 in Murowana Goslina. The record is available on microfilm from the LDS or you can order a copy from Poland as described on the above website! Good luck!
