I am looking for information on my grandfather Charles Miller born about 1885, lived in Long Island NY. I know he lived for a brief time in Chicago and my Father's birth certificate says he was 32 in 1917. He left Chicago and moved back to NY. The only other clue that I have is that someone from Social Security said he died around 1951. I have been told he was German. Does anyone have any clues on how I can find out anymore?
Thank you for any tips you can offer.
