16th Cousins, Thrice Removed
OK, this blog has gotten serious, but that's going to stop now.
According to a local publisher of geneaological software, George W. Bush and John F. Kerry are cousins. Sixteenth cousins, three times removed, to be exact. Family Forest also generated a list of other famous relatives including former presidents. Naturally, since they're related to each other, there's a lot of overlap. Bush is related to more famous people than Kerry, including Presidents Millard Fillmore and Chester Arthur, Hugh Hefner,"Wild Bill" Hickok and Bing Crosby. Both are related to Pope Gregory X (r. 1271-1276), Gen. Douglas MacArthur, Humphrey Bogart and Aldous Huxley.
Neither one of them is related to me. But my wife is related to James Monroe, so my son and wife are related to both of them.
