John W. Erwin
No history of Hamilton would be complete that did not include the name of John W. Erwin. He was born in the State of Maryland, and came out here more than fifty years. ago. When he arrived there was no railroad, no canal, and no well-constructed highway in Ohio. To these public labors he has devoted his life. He has been a civil engineer for sixty years. To him and James McBride, must be attriburted the first intelligent examination of the prehistoric relics of the State.
