Let's say it that way: I saw/heard that town for the first time. Googled it and saw on the first page only Bessarabia. Then I looked on a map of Bessarabia and didn't find the town. Next I tried it with different spellings. (I tried Stawczany, in Ukranian transliteration it is Stavchany.) Suddenly I found it near today's Lviv in Ukraine. So nowhere in Bessarabia, but in Galicia. Maybe that fits better in your family locations.
