Cornblossom was a myth created in 1958 by a Troxel descendant, then further mythologized in 1975 by a publicist for the National Parks service . Prior to that time, there is no independent evidence of her existence. If you can find such evidence, there are many people who would like to know of it.
The only known parent of Katy Troxel is Jacob per her marriage bond. He has been assumed to be the Jacob Troxel born 1758/9 in Frederick, MD and who was in Kentucky around the time Katy married there .
This Jacob’s only known spouse is Elizabeth who sought a widow’s pension in 1843. IF the 56-year-old Elizabeth Troxel of the 1850 DeKalb county census is this same widow, then she was not Jacob’s first wife nor mother of Katy
