they’re such different names.
Francés must be a real marmite name, looking at these responses. I’m sorry to say I hate is and have always wondered why anyone would call heir child something so ugly!
Madeline (the English spelling!) on the other hand, I really like. I have one and she doesn’t get called Maddie at all, either full name or Malen/Malin (kind of like saying her name really fast and eating a syllable). I’ve tried Maddie but it sounds all wrong and unnatural onher so I wouldn’t assume itd be shortened!
