As a kid, I figured Joyce KIlmer, the poet who wrote "Trees" was a girl. When I was in Vietnam, for Christmas my mother sent me a hard-bound book called "101 Famous Poems" with pictures of the poets. I checked to see if Joyce was a looker. "She" was a guy in a WW1 uniform. The caption read "Sgt. Joyce Kilmer, 69th New York, (Irish) killed in action near Ourcy, 1918."
You just can't tell by the name.

Knew a couple in Casper, WY, who were both named Rene. She was Rene', he was Renee. ( Went by his middle name, though.)

Just to settle it once and for all, Enya, Eithne, Aine and Anne are all derived from the ancient Celtic name "Frederick," pronounced "Shay-mus."
