The spelling of this may be KAMIENIEC IN Bielorus. This part was under Polish rule between 1919 & 1939 and so there may be some records available in the National Archives.It's a region with quite a chequered history got taken by the Russians after the third partition of Poland in late 18th century.
Have found a Polish mission in Kamieniec Bialorus:
The priest is :
Ks. Jan Wasilewski
ul. Podrecznaja 15
You never know he might help.
