No coincidence. Both were most likely named after famed scruffy Interplay artist, Chad Moore, who constantly aspires to be as cool as me and fails because he is too scruffy.
Chadwick Moore was an Interplay artist. He didn't do any art for the first Fallout, but he nevertheless got a character named after him - Moore, the psyker from the Cathedral. He was also a Fallout 2 artist, and he once again got a character with his last name - Thomas Moore. Both of these characters (as well as Chad himself in Chris Avellone's Fallout Bible 9) were described as scruffy.
After leaving Interplay, Moore joined Troika Games.
