A family full of eccentric, weird, sometimes insane relatives. Preferably all of them, but as long as it's the majority of them then it's okay. Commonly, it's all of them except the Only Sane Man or the Black Sheep (or White Sheep, depending on the circumstances).
Someone may observe their... "activities," but when they confront the family about this, the said family will often have no idea that they are considered to be out of the ordinary.
See also Big, Screwed-Up Family. Villainous Lineage is the darker version of this, while Heroic Lineage is the more... well, heroic version. The Professional Wrestling version of the trope is, of course, Wrestling Family. Contrast Turn Out Like His Father. Compare Shared Family Quirks.
