Hi! I am not sure if the Kuzemko I know of has any relationship to Oslawica, but he is from Ukraine. His name is Petro Tyhonovych Kuzemko, who was born around 1884-88 and was last heard of during the 1960-s. His granddaughter is currently looking for any relatives of this man - she has no family, and would like to know if Petro Kuzemko's descendants are still alive. I am helping her with this search. This woman now lives in Ukraine, the village of Medvedivka. Please let me know if you have any relation to Petro Kuzemko. Thank you so much.
