William Addams Reitwiesner of Washington, D.C., died from complications of cancer on Friday, November 12, 2010. Bill’s survivors include his mother, Homé McAllister Reitwiesner, brothers Andrew McAllister, John Stevens and Henry Pfister Reitwiesner and sister Dorothy Billopp Reitwiesner. Survivors also include his nieces and nephews, Robert, Daniel, Justin, Becky, Theodore and Thomas Reitwiesner.


After graduating from high school in 1972, Bill went to work at the Library of Congress. This was the only job he ever held. The main reason he worked there was to have access to the wealth of information stored therein.


Bill’s true passion was genealogy and he was well known for researching the ancestry of royals and other famous persons. With Gary Boyd Roberts, he wrote and published American Ancestors and Cousins of The Princess of Wales. His genealogies of American politicians were used in popular media usually without proper attribution to him. Much of Bill’s genealogical research can be found on his website,


Bill had a deep love of music. He was a long-time participant and member of the board of the Friday night Contra Dance at the Spanish Ballroom in Glen Echo. He played bass for many years in an amateur bar band in the Annapolis area.
