Nell was born on August 18, 1935 in Hillhead, SD to Ole and Dorothy Kleven. On June 4, 1955 she was united in marriage to Wayne Mannin in Webster, SD. Together Nell and Wayne had 6 children.

After Wayne's passing in 1979, Nell herself joined the workforce where she began working her first job outside of the home at an apple packing plant in Palisade, CO. A few years later, Nell returned to Lewistown, Montana with her children where she worked at various retail stores. Nell's greatest passion was spending time with her family and friends.

She was preceded in death by her parents, her husband Wayne, her brother Roger, her sister Mary Ann, her sister-in-law Marlene, her brother-in-law Malloy and many close friends.

The family would like to express their deep appreciation for Home Care Services of Lewistown. Their compassion and support of the family was beyond comforting, Thank you!
