Ted Widmer in the New York Times Magazine:
None of us can control our ancestors. Like our children, they have minds of their own and invariably refuse to do our bidding. Presidential ancestors are especially unruly — they are numerous and easily discovered, and they often act in ways unbecoming to the high station of their descendants.
Take George Bush. By whom I mean George Bush (1796-1859), first cousin of the president’s great-great-great-grandfather. It would be hard to find a more unlikely forebear. G.B. No. 1 was not exactly the black sheep of the family, to use a phrase the president likes to apply to himself. In fact, he was extremely distinguished, just not in ways that you might expect. Prof. George Bush was a bona fide New York intellectual: a dabbler in esoteric religions whose opinions were described as, yes, “liberal”; a journalist and an academic who was deeply conversant with the traditions of the Middle East.
There was a time when the W-less George Bush was the most prominent member of the family (he is the only Bush who made it into the mid-20th-century Dictionary of American Biography). A bookish child, he read so much that he frightened his parents.
