I knew a girl years ago whose given names were Yvonne Frances
; she had a nursemaid, of all things, as a baby who called her Penny
Squeaker, and she was accordingly always known as Penny
, in and out of the family. She didn't respond to Yvonne
However, once she got to university she shared digs with two other girls who happily expanded Penny
back to Penelope
and called her Lopes! (Not Lopes - lopes like a rabbit moving) And she responded happily to that as well ... if I saw her again, it's probably what I'd instinctively call her, after over 30 years.
