I'd think they got off really lightly!
I find
Sarah terminally boring, and if I meet another
Elizabeth who goes by
Liz, Elise/Elize or
Ellie I'll gnash my fangs.
Betsy is delightful, lighter and brighter than
Betty, and
Sally ... well, in today's world it's very unexpected as a nn, at least where I live. Here, Sarahs stay
Sarah and Sallys start out as
Sally. My father wanted to name me
Sarah after his late mother, but my mother declined gracefully, which I'm really happy about. But I'd have been
Sally in a heartbeat if they'd thought about it.
While you're at it, what about
Nancy and
Polly? I've only ever known one
Nancy, a British woman who went by
Nan, and
Nancy was her given name. And I know an
Anna who was sometimes called
Nan in the family as a child. I like
Nancy a lot, it dances like
Betsy. I had a distant aunt named
Mary and always known as
Polly; I like that very much too, but
Molly (which appears twice on my husband's side of the family) has always seemed to be flabby and dull.
