Wojciech Tarkowski was the son of Magdalena Ziolkowska, the daughter of the owners of the Lyniew manorial farm. In 1874, Anna Szulc's father was leasing the brewery in this farm and shortly afterwards became its owner.

In a postcard sent by Maria Szummer in 1945 from Sarnaki to her cousin (nephew) Wladyslaw Tarkowski who lived in Warsaw on Marszalkowska Street Number 72, she mentions an aunt of Tarkowski, Maria Jablczynska. This lady was in a nursing home in Wielen on the Notec River in Poland. It is not known how Maria Jablczynska was related to Maria Szummer or to Wladyslaw Tarkowski. Wladyslaw Tarkowski most probably was a son of her older half sister, Anna Tarkowska nee Szulc who married Wojciech Tarkowski in 1874.

From a note made most probably by Waclaw Szulc of people invited to a party in Grabanow before 1926 it is stated that Wladyslaw Tarkowski and his wife lived in Warsaw on Marszalkowska Street 68 and Czeslaw Tarkowski and his wife lived on Marszalkowska Street 53 Apartment 41.
