Ruby Wright, daughter of Johnny Wright and country legend Kitty Wells, was found dead on Sunday (Sept. 28) in her Madison, Tenn., apartment. According to Nashville's Tennessean newspaper, the 70-year-old singer had been struggling with heart problems for several years.

Ruby was a fixture on the 'Kitty Wells/Johnny Wright Family Show' television series, which ran from 1969 through the early '70s. Branching out from her famous family, she recorded under the name Ruby Wells, as a part of the trio Nita, Rita and Ruby. And as a solo artist, she was best known for her her songs 'Billy Broke My Heart at Walgreens' and 'Dern Ya,' which was her answer to Roger Miller's 'Dang Me.'

Ruby, who had retired from singing, was last seen publicly at her mother's 90th birthday party at Nashville's Texas Troubadour Theater. Kitty Wells is, of course, known as the Queen of Country Music. She was the first female ever to top the country charts, with her 1952 hit, 'It Wasn't God Who Made Honky Tonk Angels.'
