You know, I really like True. But I like it a bit less in the middle, because suddenly it goes from being a nifty surprise to being a one-dimensional virtue slogan-name.
I see it as feminine too - there is something Ruthy about it; strong, sensible, but kind.
Saoirse True isn't working for me. True is warm and round and almost plain, while
Saoirse is pointy and bright and insistant. Something like
Sarah True makes more sense to me.
For some reason I only want to pair it with similarily sensible and no-nonsense names, like
Josephine True,
Emily True/Amelia True,
Margaret True,
Frances True (True
Frances!),
Susannah True or
Norah True.
