My grandfather on my mothers side (Martin Andrew Kluck) was born in Zeppnov, Germany in 1862 and came to St. Louis,Mo with his parents when he was seven years old. He died in Pierce City, Missouri in 1952. My mother always told me that they dropped the Von when they came to America. Also she said he was related to Kaiser Wilhelm and to General Von Kluck. I am just getting started in my research. Hope this is helpful.
