A fascinating and persisting family legend (I call it a legend, as we have no hard proof yet) is that William Miller was a boat-builder. Some say that he build sloop ships during the Revolution for General George Washington's Chesapeake Bay campaign, but decades of research has not turned up any proof of this. [Would love to find it, though!].
