Kathleen Florence Gaab, lovingly known as Kathy, was born on August 7, 1941, in Richardton. She was the oldest daughter of Mike and Regina (Zentner) Gaab. As a young child, Kathleen moved with her parents and her brother, James, to Dickinson. The family was later joined by her sister, Linda. Kathleen grew up in Dickinson and attended St. Joseph’s School and Central High School, graduating in 1960.

On June 6, 1961, Kathleen married Herbert T. Billman. To this union, they were blessed with five children.

Kathleen worked at St. Joseph’s Hospital in the dietary department and later at the Queen City Packing Plant. She eventually stayed home to raise her five children while also helping on the family homestead, where they raised cattle, horses, and chickens. She put in a large garden every year and did extensive canning, ensuring her family was always well cared for.

She was an accomplished seamstress that created many beautiful evening gowns and clothing for her and three daughters. Eventually making numerous barbie and baby doll clothing and even Halloween costumes.

The kitchen was her happy place—she made all the German favorites, homemade bread, butter, cakes, candy, and cookies. She also lovingly baked and decorated birthday cakes for each of her children. Kathy also enjoyed drawing, especially pictures requested by her grandkids.

Kathleen and Herbert were members of the Beef Country Riders horse club and enjoyed numerous trail rides together in the Killdeer Mountains, Medora, Devils Tower, the Big Horn Mountains, and the Teton Mountains.

Kathy enjoyed bowling and was part of a bowling league. She also loved dancing polkas and waltzes, camping, fishing, playing cards, board games, and bird watching.

Holidays were always magical. She always had her house all decorated and baked goodies for everyone to enjoy. She would always wear holiday sweatshirts and earrings.

Later in life, Kathy returned to the workforce as a head cook at the Eagle’s Club and eventually became the head cook at Trinity Elementary West, where the children adored her food.

For more than 40 years, Kathy was a devoted caregiver to her husband, Herb, after he suffered a stroke.

Throughout her life, she was the steady rock of her family. Her greatest joy and passion was being a grandmother.
