If you name someone
Lindy, that's all she can be. Name her
Linda, and she can be
Linda and/or
Lindy. Isn't it a no-brainer?
Linda is a genuinely pretty name. Unfortunately, I'd expect her siblings to be
Susan and
Barbara. I think I could name a child Lyndall, but not
Linda or
Lindsay or
Lyndsey etc. I would also consider
Belinda, but I don't really think it's my style.
