Wizards, Witches and Beings: F
Fancourt,
Perpetua 
(1900 - 1991)
Witch who invented the Lunascope (fw75).
Fat Friar, the 

Was once a Hufflepuff, now is their resident ghost. He is a jolly, friendly ghost who cheerfully wishes the first years good day and hopes they'll be in Hufflepuff (PS7).
Fat Lady, the
Inhabitant of a portrait which covers and guards the entrance to Gryffindor Tower. She gets a bit irritable occasionally. She is friends with Violet. She has hung over the entrance to Gryffindor tower for many years, dating at least as far back as Molly and Arthur Weasley's time at Hogwarts. (More...)
Fawcett family
Family living near Ottery St. Catchpole (GF6). See also Miss S. Fawcett.
Fawcett,
Miss S.
(b. circa 1980)
Ravenclaw, 1991 - 1998 (CS11, GF16, GF23)
Possibly part of the Fawcett family of Ottery St. Catchpole.
Attended the Duelling Club in 1992 (CS11)
and the Yule Ball in 1994 (GF23).
For a short time she had a long white beard, thanks to trying to cross
Dumbledore's Age Line to put her name in the Goblet
of Fire despite being underage (GF16).
Miss Fawcett's dates: During the meeting of the Duelling Club, Miss Fawcett was mentioned as though she were in Harry's year. She could not have attended the Yule Ball without an older date unless she were at least in Harry's year. Dumbledore's Age Line shows that she could not have started Hogwarts before 1990. It seems a reasonable deduction that she is in Harry's year. Still, this a deduction, not something stated explicitly in canon. -- MLW
Miss Fawcett's House: There is a discrepancy between the British and American first editions of Goblet of Fire. In the first British edition, we read "'Ten points from Hufflepuff, Fawcett!' Snape snarled as a girl ran past him." In the most recent American edition, Snape deducts her points from Ravenclaw. --LWB

Finch-Fletchley,
Justin

(b. circa 1980)
Hufflepuff 1991
- 1998 (PS7)
A member of Dumbledore's Army, this curly-haired
Muggle-born wizard was down for the exclusive Muggle school Eton until
he got the letter from Hogwarts (so it is quite likely that his parents
are very wealthy). Justin was threatened by a snake at the Duelling Club
until Harry called it off, thus publicly revealing his status as a Parselmouth.
Justin was Petrified by the basilisk on
December 18, 1992.
Justin's name is sometimes given as "Fitch-Fletchley," but that is incorrect.
Fingal the Fearless

Finkley, Barnabus
Wizard for whom the Hogwarts' Barnabus Finkley Prize for Exceptional Spell-Casting is named (DH18).
Finnigan, Mrs.
Seamus' mother. He introduced her to Harry, Ron, and Hermione at the Quidditch World Cup (GF7). She is a witch, but his father is a Muggle who didn't find out until after they were married that she had magic powers. Seamus' mother read the Daily Prophet and believed that Dumbledore and Harry had gone crazy and were lying about Voldemort's return. As a result, she seriously considered not allowing Seamus to return to Hogwarts in September 1995 (OP11). When Dumbledore died Mrs. Finnigan tried unsuccessfully to make Seamus come home before Dumbledore's funeral (HBP30).

Flamel,
Nicolas 
(b. circa 1326 - d. mid-1990s)
Flamel is a celebrated alchemist (DH2) who is famous for creating the only known Philosopher's Stone in existence. As a result, Flame and his wife Perenelle (b. circa 1333) lived for over 600 years (PS17, JKR). Dumbledore did some alchemical work with him in the 1900s (PS17).
JKR on Flamel: Nicolas Flamel is an historical character. Flamel lived in France in the fourteenth century and is supposed to have discovered how to make a philosopher's stone. There are mentions of sightings of him through the centuries because he was supposed to have gained immortality. There are still streets named after Flamel and his wife Perenelle in Paris. (JKR)

Notes about using the real Flamel's
birthdate as a basis for dating the Harry Potter series
Essay: Nicolas Flamel and the Philosopher's
Stone
"According
to history, Flamel died in 1410, a few years after his wife, Perenelle..."
(pp.71-73).
Flamel, Perenelle
(b. circa 1333 - d. betw. 1991 and 1996 --JKR)
Nicolas's wife (PS17).
"Perenelle" is a play on the word "perennial'' meaning perpetual and everlasting.

Fletcher,
Mundungus "Dung"
One of the "old crowd," wizards who fought Voldemort in the 1970s. Described as a "squat, bandy-legged man with long, straggly, ginger hair (HBP12)." (More...)
"Mundungus" according to JKR, is the name of a particularly smelly
variety of tobacco (RAH).
"Fletcher" = [English] one who makes arrows (the feathers are
referred to as fletching).
Fletwock,
Laurentia

(b. 1947)
According to Jo's website, Fletwock is a "celebrated breeder and racer of winged horses" who has "campaigned for tighter restrictions on broomstick use." JKR's Wizard of the Month for December, 2006.
The name "Laurentia" (also Lawrence, Laura) is probably a
reference to the laurel plant used to crown winners of athletic events
in Ancient Greece; it is also the geologists' name for the ancient core
of North America and Eurasia.
Fletwock seems to be a sound-alike (not quite a homonym) for the word "fetlock," the
ankle joint of a horse's leg. Was this one of the names Jo came up with
when she was deciding on Professor Flitwick's name?
Flint,
Marcus

Slytherin, 1986 - 1994 (repeated a year), Quidditch Chaser and captain. Harry thought he looked like he had troll blood. He wasn’t beyond a bit of cheating to win a match (PS11, CS7, 10, PA13).
Q: In the first book you said Slytherin house Quidditch captain was sixth
year Marcus Flint. If there are only seven years of Hogwarts, why is he in
the third book?
A: He had to do a year again! :-) (Sch1)
"Flint" is a mineral known for its hardness. Arrowheads were made out of flint.

Probably a student at Hogwarts, a contemporary of Bertha Jorkins, who spied on her and saw her being kissed by some unidentified boy. Upon being hexed as a result, Bertha complained to Dumbledore, the Headmaster:
"He put a hex on me, Professor Dumbledore, and I was only teasing him, sir, I only said I'd seen him kissing Florence behind the greenhouses last Thursday..." (GF30).

Fortescue, Florean 
(d. 1996)

Florean knows quite a bit about medieval wizardry; When Harry was living at the Leaky Cauldron for a couple of weeks, he spent part of his days working on his homework at Florean's shop. Florean gave him free sundaes every half hour and helped with his essay on medieval wizardry (PA4).
Fortescue was one of the first victims of Death Eaters in the Second Wizarding War (late June or early July 1996). when he was dragged off from his shop and killed. Rowling has hinted that there was more to him than was revealed in the books (HBP6, PC/JKR2).
