Shelnitz. The earliest known record of this name is in Krasnoye at the turn of the (20th) century -- my GGGF Chayim Leib Shelnitz and his siblings. All current Shelnitzes (that are known to us) are descendants of either Chayim Leib or of Aizik Shelnitz who was - as best we know - Chayim Leib's first cousin. And there really aren't many; my father (who emigrated to Israel in 1969) has a few first cousins in the US (and I second cousins), and that's it. My brothers and I haven't done much for perpetuating the name as we have changed our name to the more Hebrew-sounding Shani.
