Mary Sue, Murray Sue, Marty Sue

[Jessie Emerson]

Does anyone know for a fact where the term "Mary Sue" came from?  Is it
indeed an outgrowth of Star Trek fan fiction?  When did "Murray Sue" and
"Marty Sue" enter the picture?

Here is some background:

"The answer is 'Mary-Sue-ism.' The term comes, I believe, from early Star
Trek fiction. To quote Melissa Wilson who wrote the excellent 'Mary Sue
Litmus Test' ( http://missy.reimer.com/library/marysue.html )and 'Dr.
Merlin's Guide to Fan Fiction':

"You already know Mary Sue. Mary Sue is the perky, bright, helpful
sixteen-year-old ensign who beams about the ship. Everyone on the ship likes
Mary Sue, because Mary Sue is good at everything. Mary Sue is an engineer, a
doctor in training, a good leader, an excellent cook, and is usually a
beautiful singer. Mary Sue often has mental powers that may manifest
themselves as telepathy, precognition, or magic. If Mary Sue is very young,
she is often the offspring of one or two already established characters. If
she's a little older, she will probably end up sleeping with the author's
favorite character. Her name is often the author's name, be it a net.name, a
favored nickname, or the author's middle name (this is seen in the most
famous Mary Sue of all time, Wesley Crusher, who was named after Trek
creator Eugene Wesley Roddenbery). By the end of the story, Mary Sue will be
in bed with the desired character, will have beamed away amid cheers from
all the regulars, or will be dead, usually accompanied by heavy mourning
from the cast. The reader, on the other hand, will be celebrating."
