In the United Sates between the nineteen-twenties and late nineteen-sixties, names that were extremely popular among females (generally among the top ten most popular names) began to be assigned to males. My own name is another example, as is the name,
Linda - among quite a few other names; I however was born shortly after this tend slowed. The name
Susan is assigned to an equal percentage of females in recent years as it was assigned to males (between the nineteen-forties and the nineteen-sixties).
