I've also only seen/heard it on males. I had an English teacher in school called
Bryn Lastname and that's sealed it as a male name in my mind.
If I saw a female
Bryn (or
Brynn) being used here I'd think the parents were very swayed by American trends so would expect siblings to be called
Madison,
Bailey,
Tyler,
Jayden etc. I hope it remains 'male' here and I've not seen it used on a girl as yet. I think it might remain male because of
Rob Brydon's character in '
Gavin and
Stacey'. Outside of Wales the programme will possibly be the only experience that most people have of the name
Bryn and there's nothing feminine about
Rob Brydon really.
I love
Bryn and
Brynn and I think I would use them.
Theodore Bryn is my second combo at the moment.
