Halcyon, Valin
this was Hal Horn's given name, since he was actually the son of the Jedi Master Nejaa Halcyon and his wife, Scerra. After Nejaa's death during the Clone Wars, Rostek Horn married Valin's mother and erased all data on the Halcyon family in an effort to protect them from Emperor Palpatine's Jedi purge. Thus, Valin Halcyon was renamed Hal Horn, in honor of Nejaa.
