Who was in the family?

Answer

The name of the father of the family was John Stauffer, Senior.
The mother was Mary Stauffer.  She died in 1875.
The oldest child was a son named Jacob.  He did not live on the farm because he was grown up and married by the time the farm was built, but his daughter, Mathilda, came to live on the farm because her mother died when she was a baby.
Eight daughters were born to John and Mary Stauffer.  Their names were Elizabeth, Mary, Rosina, Louisa, Hannah, Christina, Margaret, and Caroline.
One more son was born to the Stauffers.  He was named after his father, John.  He was the seventh child so he had three little sisters.
