Alexandra Velarde, 23, and Christian Velasquez, 19, removed from life support at Jacobi Medical Center in the Bronx on Thursday night.
Flames raced through their home, at the intersection of Trenton and Maryland Avenues, in Paterson just after 6:30 a.m. Wednesday.
Maria Velarde, 75, was found dead in a second floor bedroom.
Her husband remains at St. Joseph's Regional Medical Center with burns to the back of his neck.
Some of the 9 people who lived in the house jumped from windows to escape. Firefighters rescued others. Three firefighters suffered injuries during the rescues. The fire burned so hot that it tore through their protective gear.
The fire started in the rear of the first floor. The cause of the fire is under investigation.
