What is the best way to comfort a bereaved family

Loss of person cannot be comforted , only time will heal

Being in their side may help and lend your shoulder when they need it, time will heal everything.

You don't need to know the "right" words to say, just be there in person, sit with them, let them talk about their loved one. Cook something good that can be frozen for later, offer to babysit, take one or more of the kids on a simple outing to a park or riding bikes to give the dad a break.

Emotional support at this time is always appreciated

I think the best comfort is to do things for them I am sorry to hear this

I don't think any amount of words can soothe the grieving from the loss of a dearly beloved. The best thing that I do in those situations is to give the family space and time to grieve the loss in their own way, but let them know that they can reach out to me if they need to talk or need a shoulder to cry on. I don't enforce advice or suggestions to anyone who is grieving. I can usually feel their pain.
