In the 19th century an eccentric Frenchman willed his estate to his 12 nephews and nieces on the condition that “every one of my nephews marries a woman named Antonie and that every one of my nieces marries a man named Anton.” They had also to name each firstborn child Antonie or Anton, and each nephew must celebrate his marriage on one of St. Anthony’s days. “If, in any instance, this last provision was not complied with before July 1896, one-half of the legacy was in that case to be forfeited.” (The Irish Law Times and Solicitors’ Journal, July 8, 1905)

William Stanislaus Murphy left his entire estate to Harvard University to fund a scholarship for students named Murphy. By a will dated April 28, 1717, John Nicholson of London left the residue of his estate to poor English Protestants named Nicholson.

When Elias Warner Leavenworth died in 1887 he funded a scholarship of $900 a year for a student named Leavenworth to attend Yale. Hamilton College of Clinton, N.Y., has its own Leavenworth scholarship; it hasn’t been awarded since 1994, but, a spokeswoman told told the New York Times, “there will always be Leavenworths out there.”

In the mid-19th century it was already said that American Smiths would fill Boston Common; Mark Twain dedicated his Celebrated Jumping Frog to “John Smith” in the hope that if every honoree bought a copy, “a princely affluence” would burst upon him. Today more than 3 million Americans share the name.

This has consequences. In his 1950 book People Named Smith, H. Allen Smith reports that a desperate publicist at Warner Brothers founded the Organized Smiths of America in order to confer an award on the undistinguished actress Alexis Smith. He was surprised to find the story picked up across the country, and the awards became an annual event.

In 1942, University of Minnesota graduate student Glenn E. Smith, irritated that his professor’s lectures always centered on characters named James Smith, founded the National Society to Discourage Use of the Name Smith for Purposes of Hypothetical Illustration. Its hundreds of members pledged themselves to confront offenders with a card that read “When you think of Smith, say John Doe!”

But popularity has its limits. Smith himself was once assigned to cover the New York convention of the Benevolent and Protective and Completely Universal Order of Fred Smiths of America. He was impressed at first to find more than 40 delegates, all presumably named Fred Smith — but he lost some respect when “a man named Smith Frederick who sought admission to the banquet hall was permitted to enter walking backward.”
