Wladyslaw Stanislaw Szymanski 1. Open

I am searching for my maternal Grandfather’s Family. He was born 21 Aug 1891 in Chernigov, Poland (/Russia/Ukraine). He used various spellings for Chernigov. When he completed forms in the USA, he would identify himself as “Polish” or “Russian”. He left from Liverpool, England to New York on June 17, 1914. I do not know his parents’ names. He graduated from the Imperial University of St. Vladimier at Kiev (which I know is now the University of Kiev) sometime between 1913-1914 with a Chemical Engineer degree. A family story says that he had a brother who taught at the University. He always said he was “an Uncle before he was born”. I have his passport which is in Russian, German and French but can’t read any of the “stamps”. I have no information about him prior to his departure from Liverpool. I would love to know about his family prior. He died in 1939.
