I like Pepper. It has a fifties rebel-housewife kinda feel to it. In one of my midcentury homemaker mags, there's a contributor called
Sally Pepper Lastname-I-Can't-Recall. There's also a Jinx! It also runs along the lines of a rich heiress nickname, what
Hyacinth Bucket would approvingly call "very public school", like
Sunny or
Kiki or Harryo.
Ohh it could be a fun nn for
Penelope!
But if I was to just use Pepper, I'd pair it with something more classic I think:
