Book excerpt: "Almost since first hearing of Lady Diana Spencer ... many Americans have been aware that the Princess of Wales has genealogical links to this country ... the Princess [is] one-eighth (or more properly, three-sixteenths) American, the granddaughter of a Harvard graduate and U.S. Army captain during World War I ... she also has ancestors who lived in six of the original thirteen colonies ... and probably between twenty and thirty million living distant American cousins.".
