I now have a marriage record from the Wladyslawow Roman Catholic church, indicating that Kazimira Babianska and Julian Strzyzowskiwere married there on 19 June 1855. The town was at that time in Poland-Russia, but is now called Kudirkos Naumiestis in modern Lithuania. Kazimira's parents were Wincenty and Klara Babianski, and Julian's parents were Augustyn Strzyzowski and Kazimira Sobolewska.
I also now know that Julian and Kazimira had at least two children, Eugenija Liudvika (b. 15 June 1856) and Bronislaw Franciszek (probably b. 03 March 1858).
