I know
Ottilie is a French name, but perhaps if he came to see it more as part of the charming, old-fashioned name trend, like
Millie,
Lillie,
Natalie,
Isabelle and
Josephine. What about
Ottilie, nn
Tillie?
Anyhoo, I'm tickled that you like
Pearl so well. I had a funny feeling when I typed the combination. I'm not sure if you're considering it as a fn, but I thought I'd pass on my favorite
Pearl combination. I saw a little girl in a magazine once named
Pearl Ann-Marie (or was it
Pearl Annmarie?). Similar to your
Mariana, no?
Pearl Marianne?
If you wanted to honor your sister
Laura, how about
Daphne?
Celestine Daphne?
