In the 1880 US Federal Census for Monroe, Jefferson, Indiana, 37-year-old Indiana-born farmer John Denny did not work on the day the census was taken because he had a headache. He and his 32-year-old Indiana-born wife, Victoria [King] Denney have in their household their Indiana-born children, 12-year-old Charles, 10-year-old George and 3-year-old Cora. Charles and George work on the family farm and have attended school in the past year. Both can read, but George is recorded as not being able to write. John's parents were born in Kentucky, Victoria's parents in Baden, Germany and the children's parents in Indiana.
