I have been researching the John Preston Asbell line....not sure who John's parents were. I doubt they are Solomon and Sarah Jernigan, but John was born in TN in 1807 to a father born in NC and a mother born in MD. I believe he had a brother, Thomas Jefferson Asbell, born in TN in about 1812. Back to John Preston, his son who was another Thomas Jefferson Azbell (spelling changed in this generation) who married the daughter of a James W Davis and Elizabeth Rosson who married in Lawarence TN in 1837. (Paw Davis said his people came originally from Connecticut.) Is there any chance that somehow these Davises I'm describing are related to your Davises? I am especially hopeful because of your last name and the number of times brothers and sisters have married into the same other family.
