Ummidia gens
The gens Ummidia was a Roman family which flourished during the first and second centuries. The first member of the gens to achieve prominence was Gaius Ummidius Durmius Quadratus, governor of Syria during the reigns of Claudius and Nero. The Ummidii held several consulships in the second century, and through the marriage of Gaius Ummidius Quadratus Annianus Verus they were related to the emperor Marcus Aurelius.
