Elizabeth Bell Wade Collins

Looking for any info on Elizabeth Bell. She was born in 1812 in Hamilton County Tennessee. She married a Wade then remarried to John Collins in 1838. She died in 1850 in Tennessee supposedly in childbirth but dont know that for sure. Their is a family story that her mother was half Cherokee and her mother’s mother was half Delaware. The surname Asbury or Ashbury comes up but not for where. If somebody has information on my ggg grandmother or needs more info it would be appreciated.
