Thanks for the positive suggestions that were given, and I'm not upset by detractors, if it were not happening to us I'd be trolling this thread too.
To update this mess, yesterday I sent my GF downtown to the Appraisers Office and the realtor we purchased the house from.
It's a newer home and was built in 1998, but we knew that. Only one family had ever lived in it before we bought it according to records, and the title only listed on previous owner.
The realtor told my GF there were no deaths on record here, and it's required by law that is disclosed before the deed transfer.
We've decided to call in a medium that was recommend to us by a friend, because this keeps getting worse, and now, both of our daughters are involved.
The medium is supposed to be coming in the middle of next week and said she would call to firm it up.
The latest goings on was yesterday my GF was cleaning up our youngest daughters room and found one of her baby dolls under her bed with the head ripped off and it's eyes gouged out by a black ink pen. She's horrified, and I am too.
She ask my daughter about it and said she didn't do it, and of course, my gf ask who did.
She said it was the other little girl that lived here, so my gf says what other little girl, your older sister?
She said no, it was the little girl that was here before we moved in.
So now there is a man and a little girl.
We ruled out the dog, because there is a baby gate at the top of the upstairs that it can't go through, and no teeth marks or scratches on it, only black scratches around the eyes from what looks like a black ink pen, but we've searched all over and can't find the pen it was done with, and we don't leave sharp objects just laying around the house.
The only people in and out of the room were my gf and our youngest daughter.
We are at wits end, the things that are going on are like something is really trying to get under our skin, and it's going on with both girls now.
If this medium doesn't work, we may have to leave and move in with my mother, and that means we would both have to quit our jobs and sell the house.
My Mom lives two and a half hours away, and job prospects are not good.
