The first one is right. The dining room's where the Butler is. The little girl, however, isn't in the room with the TV. To see the girl, go to the 2nd room from the right. When she does appear, she'll be in the neighboring room to the right. Those are the locations.
By the way, I went to search for, at least, the butler today in the way I described earlier. It was sometime within the 11th hour of the day (11 AM) and took about 10 to 12 times of going in and out of the dining room before I saw the butler. So, I can say, quite certainly, that's all you gotta do.
I hope this clears things up for you. Happy (ghost) hunting!
