I'm also part of the Oracz family, most of whom are from the Kielce and Radom area.(Radom Gubernia / Kielce Province)
Enclosed is a link to my family site - you're welcome to visit.

It is known about a branch that emigrated from the Ostrow Mazowiecka area to Michigan and the United States.
Seti's sister, Leah Oracz, emmigrated in the 1920's from Wochock to the United States.
I haven't yet found a connection between the first Oracz from the Radom area, Shlomo Oracz, and the first of the Oraczs from Ostrow-Mazovieck, Leib Oracz.
All the best and good luck
