What can be some of the possible resources family should look for money in Event of Death of bread winner ?

I am trying to consolidate all relevant information ones family should know in case of death of the sole bread winner. In the event of ones death, what all are the sources his/her family can get financial benefits from? Few which I am aware of are:-

1) Life insurance(s)

2) PF & PPF

3) Employer’s Insurance benefits such as Group personal accident insurance & Group term life insurance

4) Bank – SB, FD, RD

Please share your inputs.
