I was in the fire service, volunteer and paid for over 45 years. A fire will destroy a lifetime of progress in an instant. Fire is devastating, always. I can say i honestly feel your pain and pray a speedy recovery of your losses.
Have the wife collect her dryer lint for a while. Put a layer in an aluminum pie pan and cover with used scented candle wax. Break into pieces and keep for fire starter. Works better than diesel and doesn't smoke up the neighborhood.
