Kathryn was born 23 March 1904, at Hyannis, in Grant County, Nebraska. She was a graduate of Hyannis High School, Class of 1921.

George was born on 15 November 1899, at Grafton, West Virginia, and was the youngest son of Jonathan and Miranda MORAN BUNNER's thirteen children. He arrived at Hyannis, Nebraska in 1919 where he lived with his Uncle and Aunt, Bud and Ellen MORAN. He attended business college at Lincoln, Nebraska, and worked for three years as a clerk.

Kathryn and George were married on 22 November 1923. In 1925, encouraged by Kathryn's father, Dan EGAN, George gave up his clerical job and leased the Everett MORAN ranch at Wild Horse Flats. Dan EGAN gave them a head start with a gift of livestock and saddle and work horses, as well as sharing his expertise as a master cattleman. It wasn't long before the Bunner cattle took their place among the better Grant County herds.

Kathryn worked right along side of George and was a frequent sight mounted upon her Morgan mare spending the better part of the day working cattle, and was known as a superb horsewoman. Like many western women, after working cattle all day, she would return to the house to cook and keep up with household chores. This was at a time when water for cooking, cleaning, bathing and washing had to be hauled into the house as it was not until 1936 that the "pitcher pump" and sink were added to the kitchen.

George and Kathryn worked hard to make their cattle operation prosper, and eventually purchased the Moran Ranch, as well as a portion of the John Buchfinck ranch. In 1949 they officially incorporated as the Bunner Cattle Company.

Even with the demands of running a busy cattle operation, Kathryn and George still found time to be active in the Hyannis community. Kathryn was a member of the Hyannis Women's Club and acted as the first President of the National Foundation For Infant Paralysis at its inception 23 May 1941. On 3 October 1946, she was cited by President Harry S Truman for her work with the Red Cross.

George was active on the local School Board, sitting as a member from 1937 to 1952. He was elected Grant County Assessor and served for nine years in that office, as well as sitting on the Village Board as Treasurer from 1937 to 1946.

George died unexpectedly at the Bunner Ranch on Saturday, 8 October 1955, at age 55. Funeral services were held at the Calvary Episcopal church in Hyannis, with the Rev. Willis E. Steinberg presiding. He was buried at the Hyannis Cemetery.
