I am unsure of the spelling I thought that it was Gehring not Goehring. My Grandmother lived in Lincoln Valley and was Katie.She had a Sister Magdalena they married brothers.Katie married John CD Dockter and Maggie Married William Dockter.I am pretty sure that their fathers name was Philip but I am really unclear as to their mother. Your Katherina is diferent from the Magdalena Schafer I have seen.Please email me with anything you have docconcreteguy@aol.com
