Familiar photos - Pastor Charles Obermeyer (1851-1914) was my great -grandfather , my grandmother's father on my dad's side of the family. His wife was Katherine Appich (1855-1924) - they married in 1877. The photo of the couple shows my grandparents (dad's parents), Reverand Dr. Louis John Sieck and Ottilie Obermeyer , daughter of Charles Obermeyer.They were married in 1905 in St. Louis . Grandpa Sieck and great grandfather Obermeyer were both pastors at Zion Lutheran church .
Grandpa Sieck later became president of Concordia Seminary .
My wife, who did the genealogy on my family, passed away some years ago. Her records could have more info on the Knorr family. All I can currently offer is
that Marie Katharine Knorr (1818-1900) was Charles Obermeyers mother. Will keep looking.
