I am desperately searching for Marcina (Marcena) Green Cauthorn. She was married to Albert Russell Cauthorn and died in Missouri before Albert moved to Texas with the family. She was born in MO around 1846 and died sometime before 1882. I have found their marriage date and I believe I found her on the 1860 census as M.S. Green. Aside from that she is a complete brick wall.
I am pretty sure she died while living in Audrain County.

Any help would be greatly appreciated. Thank you so much!
