Demelza is one of my favourite names. For a long time I had her as top name for a second girl. I love the fire and feistiness of it, as well as the character connection. I really started crushing on it after watching Poldark (the newer adaptation).
I also love:
Morwenna Lamorna
Lowenna (another second girl consideration)
Elowen, although I'm not a fan of the proper Ell-OH-wen pronunciation, so I don't think I'd use it.
Senara
Rosenwyn
Zennor
I really want to like Kerensa/Kerenza (espeically with the meaning), but there's something about the sound I just can't get around, it really reminds me credenza. And I like a few more Cornish names like
Caja (kay-juh), Sowenna (but I do prefer Lowenna), Gwener, and
Eseld.
And for boys I love:
Jago (didn't realise it was in the top 1000 here)
