Missed this the first time around. My mother's parents were from Kishinev (now called Chisinau), in Bessarabia (much of which--including Chisinau--is now called Moldova, between Romania and Ukraine. Part of my grandmother's family emigrated there from Romania, but I don't know when. My father's parents were both from small towns/villages near Kiev, Ukraine: his father was from Buki, and his mother from Podolye. (Here's a map showing Kishinev and Kiev.) All four of them eventually came to Philadelphia, and some time later, there I was.
