Henry Davion (b. ???? - d. ????) was the third son of First Prince Alexander Davion of the Federated Suns and the first child born to Alexander's second wife, Veronique DuVall. Henry and his family relocated to the planet Royal in the Draconis March, working to tie that world more closely to Alexander, Royal having been one of the worlds that had supported Dmitri Rostov and Laura Davion during the Davion Civil War. Over the following decades and centuries Henry's descendants intertwined themselves with the the politics of the Royal and then the Draconis March.
