Not so fast :) See Talk:Miranda (Doctor Who). While Bwburke94 is mostly right, this is an instance where T:CHAR NAMES prevails.
 * By forum consensus, the titles of articles about individual characters should be the name by which the character was most commonly known in the Doctor Who universe.

Nobody knows these characters' last names, because novelisations are really quite secondary sources. So they're better located at Bruce (Doctor Who) and Miranda (Doctor Who).
