Where can I find a certain old time record?

Okay I have a friend who's grandmother used to be famous. Her name is Linda Lee. I think she is dead now. But the way I took it she didn't make it to far. But she had some records. She made these records at "Chaparral Records", "BB Records", and "Double B Records", though these might be the same. A few of her songs include, Love Walked Out, Once a Day, Tulsa in the Rain, Road of Sorrow, and At the End of the Day. I was just wondering if anyone else had heard of her and if so I need help finding her records for a friend. The song Tulsa in the Rain was written by my friends grandfather for Linda Lee, her grandmother! Thanks in advance! :)
