Hal Horn
From the Encyclopedia of Speculative Fiction - http://encyclopedia.wizards.pro
Hal Horn, born Valin Halcyon, was the son of Nejaa Halcyon and Scerra Halcyon, adopted son of Rostek Horn, and father of Corran Horn. His name and any records of his connection to the Halcyon family were erased by Rostek Horn to protect Hal Horn from the Great Jedi Purge.
Horn became a prominent agent of Corellian Security and worked as a team with his son who followed in his footsteps. During their operations, the two were constantly antagonized by their Imperial Intelligence liaison officer, Kirtan Loor. Horn died while on mission by the bounty hunter Bossk, and Loor's choice to let Bossk escape instilled a long lasting, but unproved, suspicion of his involvement in Horn's death.
Being the son of a Jedi Hal was Force-sensitive and knew some rudimentary Force techniques - though not using the Force very often.
Behind the scenes
While referred to in many novels, Hal Horn appears as a main character in the two novellas by Timothy Zahn and Michael A. Stackpole, Interlude at Darkknell and Side Trip, in both of which he uses the Force once or twice.
