I think it's better to have a name that offers more possibilities rather than fewer. Name a girl
Betty and she's stuck with it, even if a serial killer named
Betty lives in the same town. If she'd been
Elizabeth, she could have reinvented herself with no fuss.
Even Bettina is preferable - could be
Betty,
Bettina or
Tina!
I've got a niece named
Laine and a friend named
Vickie. They both report that in times of stress, people who don't know them that well call them
Elaine or
Victoria - and that they've often just kept walking, 'knowing' that whoever was being called, it wasn't them. Tricky if it's your boss who needs to tell you that you're late for your disciplinary hearing or your mother's just died.
