Thank you for your response! According to a article in the newspaper, Stephen was born in Ljubinje. My Grand Aunt, lists his birth date as March 10, 1889. She also lists that he came to the USA when he was 16, that he was sponsered by a scientist named Pupin. The newspaper article states that he is survived by a brother in Yugoslavia. The paper is dated June 13, 1979. I try to obtain more information from my Grand Aunt, but her memory is faulty at times.
Again thatn you for your help!
