Ubaldo of Gallura

Ubaldo II (1207–1238) was judge of Gallura from 1225, the son of Lamberto Visconti and Elena of Gallura, last heiress of the Lacon-Gunale. In 1219, when both were twelve, he married Adelasia of Torres under a Pisan alliance that Pope Honorius III tried in vain to annul.

On his uncle Ubaldo I's death in 1230 he seized Cagliari, and in 1236 his influence helped secure Adelasia's election as judge of Torres, which he ruled as her consort. He died of fever at Siligo in 1238, leaving Gallura by will to his cousin John Visconti.
