Fiona Marian nn Fi / Fio.
I like
Marguerite with
Leona.
Leona just makes me think of yodeling for some reason.
Fiona I was always iffy about but then came around to it.
Funny story about
Fiona ...I have a cousin who goes by
Fiona nn Fi; it's not her birth name. She was a toddler around the time the Shrek movies came out and was a huge fan. Somehow her family started calling her
Fiona and it just stuck to this day. I don't even remember her real name.
