I have a great grandfather Frederick Armand born 7/20/1844 in Weatenberg(?) Germany to Samuel and Susanne Armand. Hef came to Philadelphia in 1846, Cinncinati in 1850 and then to Madison ,In.. He married a Katherine Schmidt, and later married Mary Kerner. Mary was the mother of all of children as far as i know. the children were :Christian John, Edward David, Christena, Frederick, William,Centennial, Maggie Elizabeth, Samuel Henry, Jesse Philip, Florence Floella (my grandmother), Mary Barbaria, and Frederick Henry.
Sounds like maybe we are researching the same line. I am trying to trace Mary Kerner but no luck so far. I have a little history on the Armand family so maybe we can exchange info.
