In the coming weeks I will publish more information here about Tevye and his life in Vilna, and also about his son Solomon who worked as an agronomist with ORT and published a thesis about a Jewish Agricultural settlement on the Polish-Belarus border that was destroyed by the Germans during the war. The thesis remains the only detailed source of information about Kolonya Yitshak, and is referenced in the on-line Sefer Zikhrones of the village.
