This couple may be older than what you are looking for but I have a Johannes Fahrner, b. August 17, 1811 in Baiersbronn, Wuerttemberg, Germany who married Regina Finkbeiner on February 07, 1837. They had 7 children, one named Johann Ludwig Fahrner, b. July 26, 1843 and one named
Johannes Fahrner, b. June 14, 1842. I don't have spouse's names for either one of them. Have more info on ancestors if these are your ancestors. Unfortunately, there are lots of Fahrners and Finkbeiners!
