My grandmother's brother-in-law Christian Justesen was born in Denmark in 1888, and he died in 1934 in Denmark, 45 years old. He was active in WWI, where he was exposed to gas, which made him ill the rest of his life. His widow got pension from the US, and she went to my grandparents, when she received letters in English from the US authorities, to have the letters translated. In 1910, he was living in Stoughton Ward 3, Dane county, Wisconsin. He was a roomer and his occupation was blacksmith (his father and brother were also blacksmiths). I have not found his WWI Draft Registration Card. What should I do next, when I want to find something about his military service? Best regards, Arne Nielsen Ballerup, Denmark
