Back to her real name, Ceybil Jefferies, she continued to work as a vocalist on several house music songs throughout the late 90s/early 2000s. Her last known solo song was "Thank U For Blessing" in 2004 and she apparently went on to sing gospel music.
According to a comment I received from YouTube, Ceybil contracted neurosarcoidosis several years ago and is now completely blind. In August of 2012, there was a surprise benefit for her which she was scheduled to attend despite her ailment.
