Scott,

Szvida, Busko, Mateleska(also Matelesko) all originated in Patskanove, former Bereg Co. I've not seen Zvorsky there but I did find the WWI Draft Registration that I believe is his and it lists his birthplace as Patskanya (He was living in Middlesex Co., NJ at this time). Szvida is a very common name in the village. I would be interested in knowing when Zvorsky arrived.
