Betty Jo Mertens, age 67, of Osage Bend, Missouri entered the Kingdom of Heaven on Tuesday, September 5, 2017 at Jefferson City Manor. Betty Jo passed from this world while surrounded by her family. She was born on September 1, 1950 at the family farm in Osage Bend, Missouri, the daughter of the late Raymond and Elizabeth (Braun) Siebeneck. She was united in marriage on October 5, 1979 to Tim Mertens, who survives at the home. Betty Jo was a 1968 graduate of Fatima High School. She was a factory worker until the birth of her first child. Betty Jo then left the work force to raise her children, home school and also help her husband with farm work.
