Family with 5 kids displaced by fire

My sister and her husband have five children, today they arrived home to find out there house on fire due to an accident. Their neighbor was burning leaves, fire got out of hand and now their house is inhabitable. Between the water, smoke, and burning the children need clothes and necessities. My teenage niece pretty much lost everything as it is her bedroom in the back. They did not have homeowners insurance. Hopefully neighbors homeowners insurance will cover the most of it, but not sure how quickly. They will be staying at my mothers house and I would like to try to get them clothes and necessities as the parents are trying their best right now to keep it together. Thank you in advance
