This is a guide to the first families of America, covering the character, career, writings, ancestry, wives, siblings and descendants of the 39 US presidents from George Washington to Ronald Reagan. This revised edition also includes essays on the presidents, with portraits of them and their wives; and pedigrees showing their descendants. The direct male line ancestry of every president is traced back to the earliest recorded origins of the family. A detailed account is provided of all progeny, living and dead, in male and female lines, and of stepchildren and adopted children of presidents.
