The Human Tarkin family consisted of several members from the world of Eriadu. They included Grand Moff Wilhuff Tarkin, Shayla Paige-Tarkin, senator of Eriadu around 22 BBY, and Ranulph Tarkin, senator of Eriadu around 44 BBY. The Tarkins had a bitter, feuding relationship with the Valorums (at least the ones living on Eriadu); however, the Tarkins were integral in helping Finis Valorum be elected Chancellor of the Republic in the elections of 40 BBY. The Tarkins became related to the Motti family of Phelarion thanks to the marriage of Wilhuff Tarkin and Thalassa Motti.
