Everything lost to a house fire

My father William (bill) Keyes lost everything in a house fire. Unfortunately he's been really sick the last few years and his house insurance lapsed. We are trying to raise enough to get the house back in liveable condition. This was my childhood home. We moved into the house in 1995. It's where all our memories are of my mother and grandmother who have both passed away. My mother passed away when I was 13, she was only 31 years old. My father had to raise all 4 of us with out her. He is such an amazing man and would do anything for anyone. We would appreciate any help at all. Thank you so much!
