The initial American Lefferts in the family was a first namer, Leffert Pietersen Van Haughwout. He arrived here on the Spotted Cow ship in 1660. The journey took seventy days across the Atlantic. Thank goodness he made it and then proceeded to marry and have 14 children. Brooklyn’s better off thanks to them. That’s true today due to the Lefferts Family Farmhouse landmark in Prospect Park, Brooklyn.
