My friend's father (Abraham Segal--originally Cygielnik) came to the United States in 1913. His city of birth was Rovna Russia. His sister arrived in America in 1922. Her naturalization records lists her place of birth as Rowna, Poland. As there are a few different shtetls with similar names, I was wondering if anyone can locate a shtetl named Rowna that was part of Russia in 1913 and then became part of Poland by 1922. Any help would be appreciated.
