David was a researcher of the New York Becraft line. His genealogy works include this and other materials he published the old fashioned way, on a typewriter. His New York Becrafts are documented in a volume that is available at the Library of Congress and you will be impressed to discover it is in a self-published mimeo style format.

David has since retired from the Becraft research and his work in this regard is well appreciated and like the other collections discussed and found to compile this website are the foundation upon which future family genealogists can begin their work.
