Chicago Firefighter Walter Stewart's three children — sons Emory Day-Stewart, 2, and Ezra Day-Stewart, 7, as well as 9-year-old daughter Autumn Day-Stewart — died in the days following the blaze, which also killed their mother, 36-year-old Summer Day-Stewart, according to the Cook County Medical Examiner's Office.
In a statement shared with PEOPLE, Susan MacDonald Stewart says that although her grandchildren "were taken too soon," they "brought enough love and pure joy into our family and this world to last us a lifetime."
"And they were deeply loved by all who knew them," she added.
