I get a really
weird image of this name, but anyway.... :P
I kind of like
Saturnina. I've never really thought about it, but now that you mention it I have a little GP-ish soft spot for it. Of yours I like
Saturnina Elanor (but I prefer the spelling
Ellinor) and
Saturnina Leonie.
Saturnina Johanna immediately sprang to mind, but I don't know if that's too much -a at the end.
I love
Artemisia, btw. It's on my PNL.
