What are some fantasy series with distinct Houses/Families?

I am looking for a Fantasy series (if there are ANY) that SPECIFICALLY has Houses/Clans/Families that have their own quirks and lore that essentially becomes what said family is known for. it can be complex like house Bolton (asoiaf) having a flayed man for a sigil because they were known for flaying their enemies which caused their castle to be known as the Dreadfort and typically produced sadistic heirs, or as simple as house Harkonnen (Dune) Baldness.
