Loss of everything in a house fire

My older sister is an amazing woman who helps everyone around her. She’s always the first to give to anyone in need. This morning her and Timmy were woken up by a loud bang! As Timmy opened the bedroom door he saw fire and smoke and heard the girls screaming from their room. Timmy slammed the bedroom door and jumped out their bedroom window with Tracey to follow. Timmy ran to the back of the house and saved their babies!!! Everyone is alive! My niece Veronica has sexond degree burns on her arms a few minor burns on her face and carbon monoxide poisoning. Everyone will be ok but they have lost their home and everything inside. Pls help these two people who would give anything to anyone rebuild a life for their family.
