I know this is an old string but this may be useful for both families...yes two Wagner families in the Theresa! Wagner -Gebhardt family is one I am related to. I have loads of info on my family tree here on Ancestry. The other family came earlier from Germany but there may be a link from in Germany because they came from the same area. I hope this clear things up...if you need more info from the Theresa area...I am a very short drive away!
