Narowlya [Bel], Narovlya [Rus], Narovla [Yid], Narowla [Pol], Naroŭla, Naroulja, Narovlia, Rovlia     Region: Minsk

Also, a soundex search on town Narowlya in the JewishGen Unified Databases:
https://www.jewishgen.org/databases/all/
finds hits with town spelled Narovli.  For instance, 119 hits in 
Belarus Duma Voters Lists.

Hits in other databases also.  Note that a phonetic search on the town name was not so productive, so choose soundex (sounds like) from the drop-down menu.
