It was actually listed in today’s nameberry blog entry:
which seems to have been referenced from a/the? French livre de prenoms. The name Laureline on the list is not linked within this site as a legitimate entry and is not listed as an international variant of [name]Laura[/name] or [name]Laurel[/name], however. It’s just my opinion but I think [name]Laurel[/name] is a good enough name that doesn’t need to be longer, but the name Laureline seems to be legitimate French alt. I prefer just [name]Laurel[/name] or [name]Lorelei[/name]. Laureline is gilding the lily, or actually the laurel.
It reminds me of my sister named [name]Lauren[/name] whom my grandmother addressed birthday cards to [name]Laureen[/name] for several years after she was born. I also think Laureline can start to sound like [name]Lurline[/name]. [name]Just[/name] an advance warning, if you want to call it that. I also once knew a Laurain. I know my sister when she didn’t think her name was fanciful enough wished her name was actually [name]Lorraine[/name] spelled like Laurain, because that girl was so cool. At least when we were young, it was just an old lady name, but now [name]Lorraine[/name] might be cool again, who knows.
