Famiglia Pitagorico (meaning The Gearloose Family), better-known as simply the Gearloose Family Tree, is a version of Gyro Gearloose's family tree drawn by Marco Gervasio.
The tree pulls together a number of preexisting Gyro relatives, though not nearly all of them, and creates several new characters to fit the gaps. The tree runs from Leonardo Gearloose (Gyro Gearloose's great-great-grandfather) to Gyro himself, somewhat curiously not including Newton Gearloose.
