I have information in my files (distant cousin Poage) that is close to yours, but your people may just be cousins to those in my files.
I have a Henry Poage (1868 - 1939) who married Hattie Poage (1870 - 1950). She was the daughter of Charles Herman Haysler (1842 - 1911) who married Elizabeth Marie Humbrock (1842 - 1917). Charles was born in Germany and Elizabeth was born in MO. Elizabeth's parents were born in Germany.
These people were in Henry county, MO.
Henry's parents were George Samuel Poage (1827 - 1882) who married Eliza Christena Kellar (1833 - 1913). You might want to check the book History of Henry County Missouri, Historical Publishing Co, by Uel W. Lamkin, 1919, which might have information that might help you. There is more information on the Poage family there.
