Connection between Bender and Benderski

My familly name is Benderski, I come from Poland.
My greatgrandfather Gabryel Benderski(1875-1957) was born on Podole (Ukrain).
My grandfather name was W³adys³aw (1925-1982), he had 2 brothers (Antoni, Józef) and 4 sisters (Weronika, Adela, Stella, Zofia). Can somebody give Me information about any of them ?
Hope to hear from You.
