The DeWitt genealogy is a fascinating study of 26 generations of the family from 1293 to the present. This work is the collaboration of descendants of the three children of Leucas, ninth child of Tierck Clafsen DeWitt. American Ambassador Lester DeWitt Ballor of UEL descent obtained a copy from The Royal Library of the Hague of Beschayving DerStad Dordrecht by Mattys Balen, Jans Zoon published in 1677. This information provided the first thirteen generations in Holland. He also received a 32-page copy of a lawsuit in 1684 by Jan DeWitt on behalf of his brother Tierck for rent owned by Pieter Janz, their sister Faelde's husband. The property was land inherited by Tierck from his father Nicholaas. It provided information on her mother Taetje Cornelisz, her father, brothers and their shipyard.
