looking for distant relatives with BILCZE', BILECZ, BIL? surname.

Grandfather (Mihaly Bilcze) anfd his brother (Lazidlo Bilcze) migarated to USA from Kiralyhaza Verocze villages of AH Ugosca county, now Korolevo Zakarpatskaya Ukraine in early 1900's.

I found some possible relatives from Szabolcs- Szatmár- Bereg megyé but nothing from this now Ukraine area.

They said may be originally from Ukraine but cannot make a connection. They were Magyar, not Ukraine.

I see there is a village in Ukraine called BILCZE ZLOTE. It is quite a distance from Korolevo but may have some connection to my BILCZE surname.

Anyone have any information on this area? How should I proceed?

Thanks in advance.
