*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25; therefore, any individual in column three is duplicated in column four.  By subtracting the number in column three from the number in column four, you can create an age class "19-25."

List is alphabetical, so no neighborhood reconstruction is possible.  Also in Mahoning Twp.:  Joseph STROUP.  Also in Columbia Co.: Andrew STROUP.
