Have you ever used/encountered games where the PCs are all related somehow (by blood or marriage)? Perhaps the group's human, half-elf, and half-orc members are all half-siblings? A group of adventuring cousins?
In 2e, we played an short lived campaign where we were all members of the same noble house. I played a bard in that one, using the Gallant kit from the Bard's Handbook. It was fun, but all too brief (sadly, we suffered from one of those DMs who never felt comfortable using D&D outside of dungeon crawls. He didn't run the game for very long.)
Or, OTOH, has a family of NPCs taken a prominent role in a past campaign: a family of wizards, a group of grown children who work for a parent, etc?
A major setting element that drove multiple campaigns in my Trinalia campaign setting revolved around the rise and fall of the Imperial house of the Empire of Drakar. There were 3 brothers and a sister, descendants of a deity and holder of the blood of kings. They each corresponded to one of the classic 4 classes: fighter, mage, cleric, and rogue.
The fighter, Dorion, was the eldest, and was a warlord type. He started the ascent of the armies of Drakar. He was brought low in a 2e campaign.
Fyre, the mage, was to take the throne in the name of his anscestor-tyrant-god Idan. He wanted no part of that, and instead of taking the throne, initiated a civil war that threatened to cast out the priesthood (including his brother). This tale is recounted here:

Fyre was eventually destroyed in a combat that unleashed a cataclysm on the land.
Tellus, the priest, assumed the throne after his brother departed and started his civil war. After the cataclysm, Drakar was in no shape to start a war. But he waited for years, slowly formulating his plan.
Shaleen had charge of the navies, and was a self-styled pirate queen. When Tellus decided not to trust any of his siblings after Fyre's treachery, Shaleen disappeared, and took charge of a loosely assembled pirate navy. She was, however, eventually captured. After PC actions in a 3e campaign that removed Tellus from the throne, Shaleen became empress to a less sinister, but not exactly nice, Empire of Drakar.
