Thanks for all of your replies...just to clarify some things, the problem I'm having with all of this is that I don't know his last name, I was only told by other neighbors about him so I don't even know if it's 100% true, kwim? So I don't want to go to the police station without this information, Mary is going to see what she can find out about him, we are the 2 newest in the area so IDK what the others know about him or why they haven't called about him living there. I did explain, as I have before, to my DDs 9 & 7 about strangers, and I specifically told them about not being allowed around Mike AT ALL. Of course they want to know why, I don't want to terrorize them but I did tell them that he is not someone that little girls need to be around. I will not be letting my DDs out of my sight at all, even if that means that they have to spend some time inside with me, until I get some more info. I even thought about having the Gfs DD come over to my house and trying to find out from her, who he is and if anything has happened to her but the mom and I already had it out over this so IDK if she will be allowed to play with my DDs now.
