Russian checker needed.

I've written some Russian characters into my DIALJ fic and I want to make sure I haven't screwed up on the names, and on one transliteration from Cyrillic.

I snaffled a couple of female surnames from the net and where I took a male surname I feminised it with -ova. Hopefully no probs, but I'd like to check that (a) they're correct and (b) I haven't inadvertently used a well-known RP name.
