Mary has long been an elusive member of the Koch side of our family, even more so than the Koch's themselves. She is the Wife of Jacob Christof Koch, the patriarchy of my Koch line. She had 8 children in her life time and was married twice, the second time to William Ott. Through her death certificate we were able to learn that her father's name was Christ Mast (which we believe is probably short for Christian or something similar). They immigrated from Germany but otherwise we know very little.
