Natalie Elizabeth Eberlein and Gustav Pluedeman, Emilia Pluedeman and Wilhelm Schenk were married in a double wedding at the Lutheran Church on Tuesday, 30 September 1892. The ceremony was performed by Reverend Theodor Nickel.

Gustav and Emilia Pluedemann were siblings, and Nathalie Eberlein and Wilhelm Schenk were first cousins.
I suspect that the members of the wedding party were also Eberleins and Schenks, but the quality of the photograph makes it difficult to identify people.
