Arthur McElhill, Lorraine McGovern and their five children died in the blaze in Lammy Crescent on Tuesday.
Two of the children, Sean,7, and Bellina, 4, were pupils at the school which is close to their home.
A prayer vigil was held as the seven bodies were removed from the fire-gutted house on Thursday.
Post mortem examinations are due to take place on the bodies later.
The eldest of the five children, Caroline, 13, attended the nearby Sacred Heart College.
The two youngest were Clodagh, 19 months, and James, who was nine months old.
All seven deaths are being treated by the police as murder. They said petrol had been scattered around the house and it had been set alight.
It is understood Mr McElhill is being regarded as a suspect.
