Halfmoon – “Let us be known by our deeds.” That was the family motto. Often when we think of billionaire families, we might think of the Rockefellers, Rothschilds, Fords and Carnegies. Their history of wealth and power transcend not only generations but entire eras of history. The Mott family, among the first self-made billionaire families in the US, is an exception to that rule.  Early in our nation’s history, the Mott family was just regular farmers. Zebulon Mott owned a farm deeded in 1795 at where Farm and Market and Pruyn Hill roads meet.
