Ruby Johnson

Could someone help me find Ruby Johnson's obituary and date of death.I believe that she would have died in the late 1980's or sometime in the 1990's. She lived in Kimball at the Nursing home there.Ruby was a former 1st grade teacher, she taught school in Franklin, Nebraska for many years.At least one of her daughters lived in Kimball but later moved away after Ruby's death.Ruby was married to my father's cousin Lyle Johnson.The first names of their daughters were Janna, Kay and Lyla Lee.Any help someone could give me would be appreciated.
