I looked up Cornish names after watching Poldark. I think they are so interesting and beautiful!
I like:
KerensaMorwenna-- I didn't used to like it, but I'm warming to it.
DemelzaJennifer-- despite it's popularity, I think it's lovely. It's crazy how none of these other names are used broadly in the English-speaking world, but this name was used so widely?
Endellion
Ysella

Trevelyan
I don't know much of anything about Cornish culture, but I am spending a few days in Cornwall this summer!
