Looking for descendants or those related to the Stanislau and Maryanna (TOCZKO) JASIULEWICZ family, or the Iuri and Wiktoria (Yanchevskix) MATULEWICZ family. I'm not sure if Wiktoria's maiden name is spelled correctly. These are my great great grandparents. Towns I have seen in various records are: Sumowo, Hultajewa, Litnak, Olszanka and Lunsk.
Iuri's son Jerzy married Stanislau's daughter Anna in 1881. My grandfathter Jozef was born in 1888 in Olshanka. His siblings were: Stefania, Urszula, Anna and Katarzyna. All but Anna went to the States.
Other children of Stanislau & Maryanna were: Julius, Franciszek, Katarzyna, Jozefina and Antoni. I have no idea if Jerzy had any siblings.
All help would be greatly appreciated.
