Hi, guys. I've just looked up Susan in the popularity lists, and lo! in the 1940s, 50s and 60s there were enough boys named Su(san) to make the charts. Too early to have been named by fans of the song ...
In those decades, Susan was remarkably popular for girls. And mistakes do creep in. But I wonder if any of you - probably Cleveland Kent Evans! - has ever met a Mr Susan, and if so, what explanation the poor bloke gave. They must explain, mustn't they? Several times a day until they die. Good grief.
Once I knew a woman, Afrikaans-speaking, whose given names were Andries Gerhardus Philippus, or as close to Andrew Gerard Philip as you can get. It seems that her grandfather had insisted loud and long that the next grandchild had to be named after him ... and she was. But all of those names could be feminised so easily. She went by Annie, if I recall.
I doubt if that is the explanation for the Mr Susans, though, because there just wouldn't have suddenly been that number of ancestral Susans with raving egos. I'm just off to check some other common female names to see if there's a pattern ...
If anyone knows, it'll be this list.
All the best
