  "At lunchtime they went down to the Great Hall, to find that the 
House tables had been moved against the walls again, and that a 
single table, set for twelve, stood in the middle of the room. 
Professors Dumbledore, McGonagall, Snape, Sprout, and Flitwick were 
there, along with Filch, the caretaker, who had taken off his usual 
brown coat and was wearing a very old and rather moldy-looking 
tailcoat. There were only three other students, two extremely 
nervous-looking first years and a sullen-faced Slytherin fifth year.
   'Merry Christmas!' said Dumbledore as Harry , Ron, and Hermione 
approached the table.....
   As Harry was helping himself to roast potatoes, the doors of the 
Great Hall opened again. Itwas Professor Trelawney. gliding toward 
them as though on wheels....
   I dare not, Headmaster! If I join the table, we shall be 
thirteen!"


No other names are mentioned. The table is set for thirteen. We get 
thirteen names.

My question is where is Hagrid?  He surely wouldnt eat alone on 
Christmas. He can't have a wife if he becomes so smitten with Madame 
Maxime in GoF. Does he perhaps have children? Or was he simply 
forgotten in Jo's writing?
