Gert married Alvin Duffert on March 1, 1960.  To this union three children were born: John, Karen, and Debbi.  They farmed and milked cows for years east of Flandreau.  They attended Lone Rock Lutheran Church, where Gert taught Sunday School. She was also a 4-H leader.

Gert took much pride in watching her grandchildren in various activities.  Holidays were spent with various family members. She was a member of Our Savior's Lutheran Church.

Gert could never leave farming totally behind.  After purchasing a house in Flandreau, she mowed the lawn for herself and three of her neighbors faithfully and enjoyed every minute of it.  She and Dallas had a great love of nature.  They would spend hours watching and counting deer and other wildlife.  When an eagle nested in Flandreau Park, they went out daily to watch the nest until the eaglets were born. She and Dallas also enjoyed fishing and golf.
