I realize this is an old posting but I do have some information on Dempsey and Mary Margaret Everett. In fact I have a picture of them. Please reply if you would like the information I have. I am a Everett by birth and have been working on this line for a long time. but sometimes all you get is unanswered questions. would be glad to share what I have. I can be reached at onyxblackcat@hotmail.com. Any help and shared information is welcome. thanks Cathy
