I am looking for information on Herman Pohl. He was married to Katherine Pfaff in 1917 in South Dakota and they had two children, Herman born 1918 and Erna born 1919 (both born in South Dakota). I would like to learn more about Herman. His son Herman died 1975. Not much is known on the older Herman. His wife Katherine was born in a country other than the U.S. and died in 1980 in California. Any help would be greatly appreciated.
