Growing up in Tampa, I was aware of Lafayette Street and the Lafayette Street Bridge and eventually in one social studies class or another learned that Lafayette was a French aristocrat who fought with George Washington in the Revolutionary War. Ho hum. Later I read a stirring account in Louisa May Alcott's An Old Fashioned Girl of a grandmother's memory of Lafayette's 1824-25 triumphal tour of the United States (at the government's invitation) -- the hubbub and excitement in the streets, his kissing the hand of the governors widow, only to discover his own face stamped on her glove, young women pelting him with flowers . . . "And here the old lady stopped, out of breath with her cap askew, her spectacles on the end of her nose, and her knotting much the worse for being waved enthusiastically in the air while she hung over the arm of her hair, shrilly cheering an imaginary Lafayette." It was this return tour when, as the last surviving general of the Revolution, he visited every state, that probably accounts for many of the streets and parks, towns, cities, parishes, and counties named Lafayette. Not to mention babies. I married into a family that preserves the Marquis' s name still -- John's great grandfather, uncle, and first cousin all three bear the middle name of Lafayette.
