This is the inside cover of a math notebook. It says "John Miller Book, April 30th 1845. John Miller ?? ?? ?? That is a lie for - it is not" I have yet to determine where John Miller fits into our ancestry, but John's mother's maiden name was Miller. The book is full of math calculations, done in pen and ink, presumably a school notebook.

Below that on a separate card is a certificate saying that John S. Detwiler was vaccinated for small pox on the 18th of July, 1924, or 1929. He was born in 1918, so he would be either 6 or 11. I found the card inside the math notebook.
