I finally found the marriage record of Frank Zalewski and his wife, Anna Lindner. The marriage took place in, at the time, Schwenten, West Prussia. Today, it is located at Święte, Gmina Łasin, Grudziądz County, Kuyavian-Pomeranian Voivodeship, Poland.
The marriage took place on 2 Nov 1884. My notes always had it listed as Jan 1885 in Poznan, Poland. While Poznan is sort of nearby, it’s not really that close to Święte. I imagine someone just picked the largest city in the area.
Click the image for a closer look. You’ll notice that Frank’s last name looks to be written as “Salewski.”
