My g-grandfather was Leo Golden Robertson, born 25 Sep 1897 in Georgia. I was just going through the 1940 census and found him and his family. He was one of the two people to have more information taken from them on the bottom of the census form. On this line, he (as the informant) stated that he was a wartime veteran with 1 year of service. On the 1930 census, he is NOT listed as a veteran. I would like to know if there is any way I can find out for sure if he served. His draft registration card is from Sep 1918, and he was single with no children at that time. I asked some of his surviving children, and they've never heard whether he served or not (they were a very private family). It seems odd to me that he would tell the census taker that he was a veteran if, in fact, he was not. Is there anything I can do?
Thank you.
