Notifying Others of Death in Family

O-o-o-kay. When Wife died, my children or I called everyone on our lists SOON, and made sure those who were called AND those on scene knew to WAIT until  MUCH later, until all vital persons were notified personally before posting the death on Social Media.
      Then, within  a few weeks, I heard through others that a family member had died. I asked how notified. "Facebook," was the answer. Some "helpful" individual had posted information almost immediately, EVEN before family had been called. I finally received a text late in the evening. Others expressing sympathy was NOT the way I wanted to hear such information.
So, Rules I suggest we follow:
1. Call  children of the deceased FIRST
2. Call his/her parents, then in-laws
2. Call both sets of brothers and sisters, asking recipient of call to pass the word on to his/her family.
3. Call close uncles, aunts, cousins who are not on others' list, again reminding person to pass on information.
4. LAST of ALL, put information on Social Media, AFTER everyone on above list has been properly NOTIFIED.

PLEASE, let decorum remain supreme.
