I got a nice facebook message from Dottie Ashley of Appaloosa:

Nice... "Momma Oh" and it is indeed about the Trail of Slaves. Got the idea for the song from a story in the Smithsonian magazine I think. Over 4 million were bought, sold,and traded, and after the war was over and people were trying to find their families, not many could read or write so they had other folks write to the newspapers for help. Of course, so many names were changed, so many people had moved, families torn apart...so tragic.
We write so many socially conscious songs. One of my other tunes was picked up by a radio station in Arlington VA for MLK weekend. It's called "Uncivil War". About Freddie Gray and Emmett Till...and Ferguson and Baltimore and how things haven't changed.
Anyway, let me know how I can help.
