Frank Johnson Hopper was born January 17, 1888, in Raymond, Illinois. He spent his twenties and thirties living in Houston, TX, where he worked as a railroad clerk for Southern Pacific Railroad. On June 5, 1917, Frank entered the WWI draft, but claimed exemption because he was the sole supporter of his parents (Garnett and Sophia Hopper). He was a short, slender man with light blue eyes and dark brown hair.
Later, Frank moved to Louisiana to do clerical work for an automobile factory. He married widower Gertrude J Cieutat in 1930 and became stepfather to her three children by her previous husband. They lived in St. Bernard Parish.
Frank died in October of 1979 in Arabi (St. Bernard Parish), LA, at the age of 91.
