In the marriage record with Emilia Snopczynska his address is listed as 45 Wielka Street in house number 1437 (now Lwowska 45).

After marriage to Emilia Snopczynska, they lived in Warsaw in the Praga suburb on the east bank of the River Vistula on Skaryszewska Street number 2.  Here their daughter Janina was born.  Later they moved to the center of Warsaw and lived on Widok Street number 22 in an apartment house that to 1919 belonged to the family of his wife. During the May 1926 Coup of Pilsudski (May 12 - 15, 1926), his wife Emilia moved out with her daughter to a manorial farm in Rokotow near Sochaczew and later moved in with her lover, Mieczyslaw Bialobrzeski.

An interesting photo survived made in 1926 just a short while before Emilia left her husband. It shows Wladyslaw Praski, his wife Emilia, Emilia's sister Natalia and Janina, the daughter of Wladyslaw and Emilia. Also present in the photograph is... Emilia's lover, Mieczyslaw Bialobrzeski, who was giving Emilia typewriting lessons.

According to the Book of Residents at Widok 22, Wladyslaw's lover and later second wife, Anna (Hanna) Steinberg (Sztajnberg), maiden name Nejman (Neuman), moved into his apartment on July 17, 1927; however, they got officially married only in 1954. His occupation is listed as a policeman (milicjant).
