I have always thought about the Kennedys when I think of this. Clearly that family views itself as circling the wagons around family and family comes first. They all have for years worked together to advance themselves and people they consider family.

Another good example of this is the Windsor family - if you ever watch "the crown" from a young age they were encouraged to support each other (even if they were unhappy with each other) and the family is always paramount.

They seem to have a higher calling for themselves and their family than most do. If I ever had a family that is what I would demand of my family. We would be a force for good in the world and with ourselves.
