Hi Wanda,
Certainly PIPERSKI (peeparskee) is from the Vojvodina region of Serbia. But Rebecca is not a name that would not typically be found there. Perhaps a bit more info would help identify your Rebecca.
1) was
KEENAN from that area also?
2) did they immigrate to the US?
3) when did they immigrate (approximately)
4) where did they settle in the US?
Those immigrating through
Ellis Is are coming from 2 areas one is
Botos about 30 NE of
Belgrade the others from Kikinda about 60 miles north.
The current online Serbia phone book lists PIPERSKI in
Botos and Kikinda.
As far as the availablility of old microfim church records the LDS Church (
Mormon) Family History Library will have them for the
Roman Catholic Church at Kikinda. If interested, and if that is the place of origin for "Rebecca", you can order them for $3.50. Those records read like a family tree.
