Help a family who lost everything in a house fire

Five days before Christmas my dad called me and told me there was a house fire at my childhood home where my dad his wife and my younger brother and sister live. The house was a total loss by the time anyone got to it, the kids lost all of their clothes and belongings as well as some family pets. Now for Christmas they are staying in a hotel instead of a house. Help give these kids buy clothes and everything they need plus some Christmas gifts
