Help with funeral costs for grieving family

My name is Roland. My mother and stepfather were killed the weekend of June 14th 2025. Us remaining children are trying to come up with burial and funeral costs, as well as living costs for the several young children. My mother was the most selfless person I've ever known, and cared so much about her children. I'm doing my best to fulfill her wishes by providing the children stability as I deal with the situation. Thank you.
