chrystynakells,

Toporowcz = Toporivtsi = Топорівці (Cyrillic). This village in the Horodenka raion (area) has a population of 2000.

I believe that your family name Mochouk should be spelled Mochoruk (Мохорук - Cyrillic). According to my phone directory, there are Mochoruk individuals still living in Toporivtsi.

Note: There is also a village Toporivtsi in the Chernivtsi oblast (region).
