Hey, Jane_Doe have thought of looking thru Google (or any other engines that have them) Groups? You can then dig for what folks may be saying 'about' those sites and go from there.
Here are a couple of sites which may be helpful.
http://www.cyndislist.com/ for geneology.
http://vitalrec.com/ vital records listing.
http://www.brbpub.com/ Public Record Sites listed.
Don't worry if these are where you've already been because NGs are not too prohibitive of posting links to those they feel are the good ones, so you'll find more.
Oh, your quest may have much better results if you can dig up any/all background information on all parties involved before you start looking around. Any SS#s etc., Employment history, any Military duty and so on.
The idea of collecting your tracable data first will go a long way in reducing any false listings or wild goose chases.
Best Wishes on your journey and may it be very, very fruitful. :)
If there is anything else you need, let us know.
