I am Robyn, when I was a bump I was “Bob” from blackadder. Occasionally when I was a child people would call me Rob but I’d just correct them and say I didn’t like it and no one tries to shorten my name as an adult. I quite like my name! Agree with other posters saying Robin for a boy is a bit “wet” though.
And as a girl, I’d hate if my name was spelt Robin not Robyn 😂
