The publication The Ancestry of Catherine Middleton has just been released by the New England Historic Genealogical Society in Boston. The genealogy's author is the late genealogist William Addams Reitwiesner, while Christopher Challender Child has edited it. The foreword is written by Gary Boyd Roberts. As described by the publisher, the work contains the ancestor table of Catherine Middleton as well as more than twenty charts illustrating Kate Middleton's relationships to various figures of historical and cultural importance, including President George Washington, WW2 General George S. Patton Jr. and Director Guy Ritchie. See also the articles Which of Kate Middleton's Ancestors is also a Common Ancestor to Millions of Americans? and Is Kate Common?, which includes a CNN interview. Another article by Associated Press is published by the Canadian Thestar.com.
Kate Middleton is apparently a 8th cousin seven times removed (!) to President George Washington and a 14th cousin once removed to her fiancé, Prince William of Wales.
The book costs USD 29,95 + P&P (I have just ordered it!)
