I don't know whether the Facebook group is still active, but I hope not. I reported illegal activity there when I began to receive death threats from someone in the group. I don't find that sort of thing amusing at all.
Ancestry.com is another group that has amazing information however, it isn't free. I believe that they offer a free trial, though. That's where I have posted all of my information. Many Maryland Geisinger's there.
Good luck! Ron
