Name's cross or change genders pretty often, usually with variations in spelling, but not always. Ethel, Marion, Madison, Michael, Sydney, Danny, Willie, Bobbie, and on and on and on. What fun! I want to change my name to Britney...not really.
i have a "marie-georges" sister as a french teacher in school, and every other sisters had male name with for most of time marie adding "soeur marie-pierre' etc...in french, it was really common 50years ago to have those female male-based names
