Martha Deter Mason

My great, great Grandmother's, birth name was Martha Deter. She was born, April 5, 1848. She later married, my great great Grandfather Asa Mason. Thus, giving her the name, Martha Deter- Mason. She died, February 18, 1885. I am looking for, the names of, her parents. This will help me, finish the Mason/Deter side of, my Family Tree.
