And I almost forgot…
My paternal grandmother has gone by the name “Dick” all her life. Yes, she’s and 83-year-old woman, and still answers to “Dick”. She has two sisters who still answer to “Pete” and “Johnny”. You see, their father wanted sons, and was blessed with daughters on the first three tries. They all have proper female names - my grandmother’s is Lorena, (and to this day I have no idea what my great aunts’ real names are) but only use them on “official” documents.
Their younger brother grew up suffering with people, who knew his sisters, thinking it was funny to call him Mary. Come to think of it, I don’t know what his real name is either. I’ve never met him.
And somebody mentioned boys named Sue… I had a Korean-born friend (via the Internet) who arrived in the USA when he was five years old. His given name is Soo. He went by Keith when he was growing up, but as an adult decided to go back to his original, Korean name.
