JoAnn Mary Cordell was born on October 19, 1936, in Codington County, SD, to Peter John and Katherine Marie (Jellesma) Cordell. She was the fifth of eight children born in the family home. JoAnn was baptized and confirmed at the Immaculate Conception Catholic Church. She attended grade school at Immaculate Conception School through ninth grade and graduated from Watertown High School in May 1954. She was the first family member to graduate high school.
Growing up, JoAnn babysat her siblings and the neighborhood children. She also assisted her mother during harvest time by picking, cleaning, washing, and cutting vegetables. She helped plow the fields. JoAnn and her brother Jim would race to see who plowed the most, with Jim always winning. She also drove the fully loaded grain truck several times to the Rauville Elevator for her older brother LaVern. During the winter months when the snow became too deep to travel, Dennis, Jim, and JoAnn walked over snowbanks as high as trees to the north corner to catch a ride in a wagon with their uncle John Cordell and his grandkids. Uncle John drove them a mile to the corner of Highway 81 to catch a ride into Watertown for school.
JoAnn’s first paying job was making candy and helping customers at the Palace of Sweets during the summer of 1953. She also worked at the Lyric Theater, Dan’s Standard Gas Station, and National Food Stores. JoAnn worked three jobs and saved enough money to cover expenses to attend high school (lunch, class ring, class pictures, and clothes). This money also helped JoAnn pay for gas for the car she purchased in 1954-55.
After high school graduation, JoAnn worked for Jack Hoffman and Fireworks Outlet. JoAnn met Wendell Gnat shortly after he was discharged from the U.S. Army. They married on December 30,1957, at Holy Name Catholic Church in Watertown, a church her father, Peter, had helped build. JoAnn and Wendell lived in a small house north of the home in which JoAnn was raised. Wendell and JoAnn moved to Appleby, SD in May of 1962. They started with one cow and made monthly payments until the cow was paid off. Several years later, they had purchased many cows, pigs, and sheep, and they farmed 200+ acres.
Other jobs include working at Watertown Title Company as a real estate typist searching for titles; Dean Sumner, Attorney, as a legal secretary; Koehn Manufacturing as an accounting assistant; and Prairie Lakes Hospital (St. Ann’s) as a personnel secretary.
JoAnn was a 4H leader for the Appleby Boys & Girls Club for 2 years, a financial secretary for 6 years for the Catholic Daughters, a secretary for Codington County Democrats for 6 years, and county chairman for 2 years. JoAnn oversaw fundraising and obtained speakers for banquets, with Senator George McGovern and Senator Tom Daschle being some notable keynote speakers. She ran for the office of the Register of Deeds in Codington County and won the primary by 13 votes but lost the general election. In 1989 after their children had moved away, JoAnn and Wendell sold their Appleby farm, had an auction and moved to Omaha. After moving to Omaha, JoAnn volunteered three days a week at the Veterans Medical Hospital and served on the Election Board for several years. She was involved with the “Stand Down for Veterans” with her sister Karen. JoAnn then began her favorite job at the U.S. Army Corps of Engineers (COE) for the next 5 years. Next, she transferred to the U.S. Department of Agriculture for 10 years before retiring on January 20, 2007, at the age of 70. After her retirement, Wendell and JoAnn moved to Huron to be closer to family, and in 2011, they moved to Sioux Falls to be closer to medical facilities for Wendell. JoAnn moved to Miller in May 2023.
JoAnn is survived by her children, Edward (Ellen) Gnat, CA, Rodney Gnat, FL, Jody (Damon) Adams, Madison, SD, Gerry Isackson, Huron, SD, Jeffrey (Tammy) Gnat, Miller, SD, and Joel (Heather) Gnat, Ham Lake, MN; 17 grandchildren; 31 great grandchildren; 5 great-great grandchildren; sisters-in law & brothers-in-law, Bob Goodell, Shirley Cordell, and Dorothy (Adrain) Pratt, Anita Gnat; and numerous nieces and nephews.
