Could this family have been in Putnam, OH in 1880? I found a John Kalt, married to Maria with 7 children. They were in Monterey township. The children are:
William, age 16
Emma, age 15
Charles, age 13
Maria, age 8
Frank, age 6
John and Anna (twins) age 4
If these are part of your family, I'd like to hear from you.
