At best, all we ever see of debonnair detective Charles Townsend on 'Charlie's Angels' is the back of his head as he gets a massage, usually only his arm. Henry Branham, Jr., who runs the "Charlie's Angels Forever" website, compiled the salient facts about Charlie:
"Since Charlie has so many acquaintances at the police department, it can be assumed that he started out at the bottom and worked his way to the top. After years as a police officer, he possibly moved up the status of lieutenant and from there he would go on to open his very own detective agency.
He was once married but confessed to not be the monogamous type, and it is never indicated whether or not he has any legitimate children."
Here are a few TV characters bearing the Townsend surname who may or may not be related to the mysterious Charlie Townsend:
Townsend* (Roswell (1994), Martin Sheen)
Taylor Townsend ("The O.C." (2003), Autumn Reeser)
Max Townsend ("Dracula: The Series" (1990), Jacob Tierney)
Christopher Townsend ("Dracula: The Series" (1990), Joe Roncetti)
Matthew Townsend ("It's Not Easy" (1983), Billy Jayne)
Neil Townsend ("It's Not Easy" (1983), Bert Convy)
Nick Townsend ("CSI: Miami" (2002), Rob Estes)
Pa Townsend, Frankie's father ("Windfall" (2006), David Newsom)
*The character played by Martin Sheen in the "Roswell" TV movie (NOT the TV series), could have been an older brother or even Charlie's father - if it can be determined that he was using his real name when dealing with Jesse Marcel.
I left out several others who at best were connected far too many generations back, as they were all British.
