Blaine Joseph Keppen was born June 28, 1926, the son of William “Billy” & Anna (Eschenbaum) Keppen on a farm south of Zell, SD. He attended St. Mary Convent School in Zell until the family moved to Madison, SD in 1936. He went to St. Thomas Aquinas School while his family ran the Virginian Cafe. In 1938, his family resumed farming in Orland township. Blaine graduated from Orland at age 16 and farmed with his father, while his brother Clare, was in the United States Navy Aviation in the South Pacific in World War II. Upon his brother’s return in 1946, Blaine enlisted in the Army and served in the Allied Occupational forces in Trieste, Italy.
Blaine met Bonnie McAllister on a double date and became engaged in 1949, but he was called up as a reservist in 1950 during the Korean War. He was wounded during the Battle of Wonju in February 1951. After recovering, he finished his duties in the 8th Army Honor Guard. Blaine and Bonnie were married December 20, 1951 in Madison, SD and celebrated a 65th anniversary shortly before her death in January 2017. Blaine and Bonnie farmed in Orland until 1988. A tornado destroyed the farm in 1993 prompting a move into Madison.

Many Sunday mornings were spent milking the cows in the wee hours of the morning before early mass. He was a clerk and later a full member of the Orland School Board. In retirement, Blaine and Bonnie spent winters in Southern California, Arizona and especially the Rio Grande Valley of Texas. He fished year-round including through the ice.
