Thanks Eugenia; I have also found this 'Czyzski' and another few more who were in the Orthodox church. Given that the surname is rather uncommon, there could be a link between some of these men and ours.
re my story. My grandfather was 'Jakob Czyzski' (and most probably variant spellings), he was Ukrainian and married my grandmother somewhere in Ukraine (location unknown). She was a Polish catholic, her name was Stanislawa Tarnogorska and was born at Koziatyn (Ukraine) in 1897.Their first daughter was born at Zdolbunow (Ukraine) in 1919.
Then the family moved to Poland where my mother was born in 1921. In about 1924 grandfather Jakob vanished, never to be heard off again, and apparently contact with his family in Ukraine also failed.
What we know from oral tradition is that Jakob's father was a priest in the orthodox church and that Jakob had many siblings. All these children were good musicians, each playing a different instrument so that during feasts like Easter it was apparently like an orchestra playing at home.
Well, that is all we know. Our extended family would dearly like to find out what happened to Jakob. We would like to make contact with members of his extended family, if there are some alive today, just to know more about them all. We feel that making contact with a 'Czyzski' who is in the Orthodox church in Ukraine could be a good start.
