Harry was the youngest son of Mr. and Mrs. John Kupferschmidt. He grew up on his parent's homestead seven miles west and one and a half miles south of Ypsilanti, North Dakota. Luella Cumber was also raised in the Ypsilanti community, in Corwin Township, Stutsman County.
Harry and Luella were married in 1932, and farmed throughout their married life. In 1982, when the Ypsilanti Community Centennial Book was published, Harry had passed away, and Luella was still living on their farm.
Harry and Luella had two sons, Richard and Donald.
Richard married in 1979. He and his wife, Mary, lived in Ypsilanti for a short time, while they were building their new home on their parent's farm site.
