Lin- Disregard my Jill Anderson link. I'd been working on this since before your mentioned that you've already been able to discount her as a possibility.

Some clips from Geraldine MacGowan (note spelling) here. at least you can hear her voice to see if it rings a bell, and contact information seems to be available there. http://geraldine-macgowan.com/?page_id=28

That's all I have time for.
