I pronounce it the British way, unsurprisingly. My best friend is
Carolyn, pronounced with -lin.
It's a good name, a timeless classic which seldom attracts nns; I've always liked it but never thought of using it until my new-born daughter surprisingly looked like a
Caroline. I didn't know then and don't know now what that means, but it certainly happened and we were very happy with it.
I don't like
Wren or
Hazel.
Caroline Rachel;
Caroline Alice;
Caroline Clare;
Caroline Janet (my friend is
Carolyn Jane).
Siblings:
Peter and
Lucy;
Ian and
Ruth;
Keith and
Louise
