The History of Alexander Henderson Elementary School
Alexander Henderson (1738-1815) was a colonial merchant. He was born in Glasgow, Scotland and came to Virginia in 1756, moving to Dumfries in 1787.

He was a delegate to the Mount Vernon Washington. The Mount Vernon Conference of 1785 led to the Constitutional Convention of 1787.
