Name for sour, stuffy character?

I need a name that sounds priggish and slightly old-fashioned for the sister of one of the noblemen in my story, whose name is [name_u]Ashley[/name_u]. She’s, by the standards of this society, an unpopular spinster, and is very resentful of the whole thing, but she’d do anything for her brother. Kind of minor character, but I’m stuck. Last name is Verton. Nothing too fantasy-ish, preferably English-sounding.





Good luck!

[name_f]Katherine[/name_f] or [name_f]Cathrine[/name_f]

(Sorry but I could use some help naming my main female character. If you can check out my post that would be wonderful! Nameberry - Welcome to the Nameberry Forums)
