Wesley and
Penelope are great together.
Juliet is not my style, but fine as a middle name. It's not too much, imo.
I've never liked
Penny as a nn for
Penelope, it reminds me of money.
Till now, my favorite nns for
Penelope were
Nell,
Nellie,
Pippa, Pepper and Nolly. I've never thought of
Poppy as a nn for it before and I think it's great. I'm adding it to that list.
