He was one of 13 children born to Joe and Bobby Sue Rager.
Mose married Laverda Maxberry on Aug. 28, 1934. They were the parents of Gayle, David, Anita, Marilyn and Freddie.
Mose Rager was a musician. He began playing the guitar when he was about 7 years of age. He grew up amid family members who picked and sang. Mose studied other guitarist' technique in and around Muhlenberg County. He would team up with Ike Everly or Plucker English to create twin-guitar duets for local dances.
At the age of 15, Mose started working in the coal mines, like many other boys at that time. By the mid 1930's he had settled in Drakesboro, KY where he operated a barber shop and worked part-time in the mines.
In 1943, Mose decided to make an attempt to enter into the music profession. He worked with Grandpa Jones for awhile and then with Curly Fox, a very popular fiddler.
Despite his success, being on the road did not appeal to Mose so he returned to Drakesboro.
Mose gave guitar lessons, played in local bands and enjoyed the success of his good friend and former pupil, Merle Travis. Of the many musicians who influenced Merle Travis, Mose Rager is said to have been the most dominent.
