Middle Name Help

[erikalyn.livejournal.com]

I think I've just about decided on the first name for my baby girl due in May but I'm having some trouble with middle names. I would like to honour my mother somehow but I'm not a huge fan of either of her names (Karen Ann), so I'm looking for some other variations/names I could use that would still honour her without being the exact same name. All I've been able to come up with is Katherine, which doesn't exactly make me all warm and fuzzy inside. Help!

Stella (insert middle name here) Trenholm

EDIT: I found one I like, Katrine, but I would still like to hear other suggestions :)
