I heard an interesting interview on the radio today.
It was based on this video: https://www.youtube.com/watch?v=IDK6iYeU1aM
and was from the Canadian Association of Men with Women's Names.
Apparently, Canada has the greatest percentage per capita of men with women's names and it does cause personal and professional issues for them. I didn't realize that a support group had developed around the issue though!
Except, many of those names were once male names, before being adopted as women's names.
Kelly (Variant of Ceallach, an Irish masculine name)
Tracy ("Charles Dickens used it for a male character in his novel 'The Pickwick Papers' (1837). It was later popularized as a feminine name by the main character Tracy Lord in the movie 'The Philadelphia Story' (1940)")
Ashley (Until the 1960s it was more commonly given to boys in the United States, but it is now most often used on girls.)
Jesse (Father of King David in the OT, also Jesse James, and athlete Jesse Owen) -- Jessie is a variant, also masculine as well as feminine.
Sandy (Originally a diminutive of Alexander. )
Kim (Scandinavian short form of Joachim; also, "The author Rudyard Kipling used it for the title hero of his novel 'Kim' (1901), though in this case it was short for Kimball." (a masculine name)
Laurie (a diminutive of Laurence)
Terry (from an English surname, also diminutive of Terrence)
Nicky (diminutive of Nicholas or Nicole - so m&f)
Leslie ("It has been used as a given name since the 19th century. In America it was more common as a feminine name after the 1940s.")
Courtney ("As a feminine name in America, it first became popular during the 1970s.") << pretty recently feminine. I actually knew a man named Courtney. There's nothing feminine about him.
Stacey ("As a feminine name, it came into general use during the 1950s, though it had earlier been in use as a rare masculine name."
