Funeral cost for my niece and her 2 children.

My name is Catherine. Earlier this morning I got devastating phone call. My niece was heading back home with her 4 beautiful little girls. Ages 2 to 7. From visiting me and my parents here in Tennessee. She was on the way back home to NH and she was hit by a Semi truck in Virginia. Her and 2 of her children were killed. The other 2 as of right now are in stable condition. Let's hope and pray that it stays that way. I am setting this up to help my nieces husband with funeral cost, travel and time out of work to care for his children, until they can heal. So any help would greatly be appreciated.
