She already inquired about it in February last year, under another Lilly's nick, and was given a probable name Szuski by Polonius3.
Lilly1953:I would say, short names like this, sounding Polish, but with no particular meaning attached, are very likely Jewish. The Prussian and Austrian administration followed some strange patterns when assigning names to Jews in 19 c. Other typical examples of Jewish short names are: Orski, Zorski.
There are hundreds of references related to this topic, do your own work, Lilly. Here are just two, randomly chosen.
