Studies showed that children with odd names got worse grades and were less popular than other classmates in elementary school. In college they were more likely to flunk out or become "psychoneurotic." Prospective bosses spurned their résumés. They were overrepresented among emotionally disturbed children and psychiatric patients.
Some of these mental problems might have been genetic -- what kind of parent picks a name like Golden Rule or Mary Mee? -- but it was still bad news.
Today, though, the case for Mr. Cash's theory looks much stronger, and I say this even after learning about Emma Royd and Post Office in a new book, "Bad Baby Names," by Michael Sherrod and Matthew Rayback.
