How interesting - thank you! Must say, I'm surprised it caught on ... though not in a big way, seemingly. There've been some suggestions lately on Babycenter.com that
Lorelei is being used now and then as a girl name in the States, mostly among people who don't know the legend.
Arline interests me greatly, too! In, especially rural, Afrikaans communities here in South
Africa there is a strong tradition of naming children after the grandparents, often in sequence. So you will get cousins growing up on adjacent farms, all with the same names. Nicknames come in handy, also the name of the farm as a kind of additional human name. So it was that I was at school with three girls, cousins, all named
Alice Marsephine. The Marsephine is a lasting mystery to me ... perhaps a long-ago
Josephine had a fondness for marzipan! One of them was known as Marzie, one as
Alice, and the remaining one had been
Alice too until, as a very small child, she discovered that there were two of her and announced to the world that she was
Arline. And so it was. She seems to have invented it independently ... I've more often seen it with an -e- spelling, like
Marlene with the M missing.
All the best
