Jeff Burns Married to Lucinda don't have her Madian name or there marriage date if he died or divorced.I do know they had 6 children
Bob Burns
Munk Burns
Bill Burns
Calley Burns
Sara Ellen Burns
Effie Lucreica Burns ( My GrandMother)

Then went on to Marry Henery Rains & had 2 children
Mary Rains
Wallace Rains
I think Jeff Burns was full bood Cherokee indian i'm not real sure.
