Wizards, Witches and Beings: T
Tatting 
Presumably the co-owner of Twilfitt and Tatting's, a wizarding dress shop (HBP6).
Thickey, Janus

In 1973, Thickey left a note on the bedside table for his wife, claiming that he had been killed by a Lethifold. Janus was shortly thereafter discovered five miles away, living with the landlady of the Green Dragon (FB). A ward for patients with spell damage in St. Mungo’s Hospital is now named for Janus (Gilderoy Lockhart and the Longbottoms reside there), which suggests that he might have come out of this incident a little worse for the wear (OP23).
"Janus" was the two-faced deity after whom the month of January was named.
Thicknesse,
Pius 
Minister for Magic from 1997-1998 while under the Imperius Curse (DH13,36). (More...)
Pius=To be 'pious' is to be noticeably and devoutly religious or obedient;
today the word can sometimes imply hypocritical behavior. 'Pius' is an
old Roman title used by emperors, and later, by Italian Popes.
Thicknesse='thick' is slang for stupidity.
Together his name would appear to mean 'pious stupidity,' an inauspicious
name for a Minister of Magic.
Thomas,
Dean

(b. circa 1980)
Gryffindor,
1991 - 1998; Quidditch team Chaser (HBP14, HBP24).
A "half-blood" Black boy, even taller than Ron (PS7, OP11).
Member of Dumbledore's Army. (More...)
Thomas, Mr.
Biological father of Dean Thomas, a wizard
who walked out on his Muggle wife and infant son to protect them from the Death
Eaters. Thomas was eventually killed by the Death Eaters when he refused
to join their cause (
JKR). Sadly, his son doesn’t know why his father left, or even who he was (DH15).
Thruston,
Orsino
(b. 1976)
Plays drums with the popular wizarding band The Weird Sisters (fw98).
"Orsino" = refers to the Count Orsino inTwelfth Night. Orsino was the mouthpiece of the line "If music be the food of love, play on." Of course, since JKR's Orsino is a drummer for a popular wizarding band, this is not without her trademark irony. It's even more so, because Orsino was actually speaking negatively of love, with the music as a means to over-feed him, to make him weary of love.
Thurkell,
Thaddeus
(1632 - 1692)
Famous for producing seven sons, all Squibs, and turning them all into hedgehogs in disgust (fw).
Tiberius

Uncle of Cormac McLaggen. Tiberius was a favorite student of Horace Slughorn's. Avid hunter; his hunting buddies include Bertie Higgs and Rufus Scrimgeour (HBP7). He holds high office in the Ministry of Magic. It is possible that 'Uncle Tiberius' is Tiberius Ogden.
Timms, Agatha
Owner of an eel farm, she bet with Ludo Bagman over the Quidditch World Cup match (GF7).
"tiny old wizard in violet cloak"
One of the first wizards we meet in the books. He bumps into Vernon Dursley at 5pm the day after Voldemort disappeared and said "Don't be sorry, my dear sir, for nothing could upset me today! Rejoice, for You-Know-Who has gone at last! Even Muggles like yourself should be celebrating, this happy, happy day!" Then the old man hugs Dursley and walks off (PS1).
Rowling uses this encounter to show Dursley's profound discomfort with anything unusual or magical. This wizard is possibly also "tiny man in a violet top hat" that bowed to Harry while he was out shopping with his aunt (PS2).
Tofty
Member of the Wizarding Examinations Authority, he is a friend of Tiberius Ogden and an examiner for Harry during his practical Astronomy, Charms, and Defense Against the Dark Arts O.W.L.s and History of Magic theory O.W.L.. Tofty wears pince-nez glasses and appeared to be the oldest and baldest examiner, with a quavery old voice (OP31).
Toke,
Tilly
(1903 - 1991)
Recipient of the Order of Merlin First Class as a result of the Ilfracombe dragon attack of 1932. An errant Welsh Green dragon attacked a beach full of sunbathers. Tilly and her family were credited with saving Muggle lives as well as wiping their memory afterwards. One Muggle, however, known as "Dodgy Dirk," is known to tell tales of a "dirty great flying lizard" that attacked him way back when. His story is not believed by other Muggles. Tilly now appears on a Famous Wizards card (#77) (FBxvi, fw77).
Tom
Bald, toothless, gloomy old innkeeper of the Leaky Cauldron (PS5, PA3, PA4). He was succeeded by Hannah Abbott (OBT/CH).
Tom was played by Derek Deadman in the first film. He is not depicted as either bald or toothless (PS/f).
Tonks, Andromeda "Dromeda" Black
(b. before 1955)
Though a sister of Bellatrix Lestrange and Narcissa Malfoy (and very similar in appearance to Bellatrix), Andromeda married a Muggle-born, Ted Tonks, was promptly blasted off the Black family tree (BFT, DH5), and had a daughter, Nymphadora (OP6). Nymphadora was born in 1973 so Andromeda probably started Hogwarts in the early to mid-1960s, making her older than her cousin Sirius. Andromeda was Sirius' favorite cousin.
Andromeda helped the Order of the Phoenix during their war against Voldemort, a war in which her husband, daughter, and son-in-law, Remus Lupin, were all killed (DH22, DH34). She then single-handedly raised her grandson, Teddy Lupin, though she had plenty of help from family friends (BLC, DH/e).
Tonks,
Nymphadora
(1973 - May 2, 1998)
Appearance: as a Metamorphmagus, Tonks could assume many different appearances. Her actual appearance was that of a pretty, young woman with a pale, heart-shaped face. Married to Remus Lupin. She preferred to be called "Tonks" but her father calls her "Dora." Killed at the Battle of Hogwarts (DH).
A "nymph" = a mythological semi-divine maiden. (More...)
Tonks, Ted
(d. 1997)
Muggle-born wizard, father of Nymphadora and husband of Andromeda. He was described by his daughter as a "right old slob," in contrast to the Dursleys, whose house seemed unnaturally clean to Nymphadora (OP3). Andromeda's marriage to Ted resulted in her being disowned by the Black family (OP6). Ted Tonks had fair hair and a large-ish belly (DH5). During the war on Voldemort, Ted tried to run from the Ministry (DH15), but was caught and killed (DH22).
Toothill,
Alberta
(1391 - 1483)
Famous Wizarding Duelist. Toothill won the All-England competition in 1430 with a Blasting Charm. She defeated Samson Wiblin, who was the favorite to win. Toothill now appears on a Famous Wizard card (and Wiblin doesn't!) (fw27).
Both "toot" and "blast" are slang terms for "fart."
Toots,
Tilden
(b. 1959)
Radio Personality. "Bouncing bulbs losing height? Devil's Snare merely tickling? Fanged Geranium nothing but gums? Then tune your wireless to Toots, Shoots 'n' Roots the award-winning herbology presented by ~Tilden Toots,~ 'the wizard with three green thumbs'" (JKR). Toots is married to author Daisy Hookum and has a broad West Country accent.
You can listen to Toots'
radio show by turning on the radio in the "Extras" page of
JKR's
website. On that show he tells Georgina
Smythe how to revive her Flitterbloom plant
(and thus tells us how to revive the one on the Locked
Door page as well). He was JKR's Wizard of
the Month for March 2007 (JKR).
Towler, Kenneth
(b. circa 1978)
Gryffindor 1989 - 1996.
A student who took his O.W.L.s at the same time as Fred and George, who developed boils as the test approached. Granted, the boils had a lot more to do with the Bulbadox Powder Fred had put in his pyjamas than with the stress of the test (OP12).
Travers
Death Eater who Murdered Marlene McKinnon and her family, according to Karkaroff during his own trial; he had already been captured by the Ministry (GF30, OP9).
Travers later escaped and went back to work at the Voldemort-controlled Ministry of Magic (DH13); he also had a most unfortunately timed encounter with a woman who he thought was Bellatrix Lestrange, going into Gringotts, though it was actually Hermione preparing to break into Bellatrix’s vault. Harry quickly placed him under an Imperius Curse and made him hide in a crack in the wall of the cave tunnels (DH26).
Trelawney,
Cassandra 
Great-great-grandmother of Sibyll Trelawney. Cassandra was a "very famous, very gifted" Seer in her day (OP37).
Cassandra=Trojan seer gifted with true prophecy, but cursed (by Apollo) so that no one would ever believe her. The people of Troy ignored her warnings not to allow the Trojan Horse within the city's walls, a mistake that allowed the Greeks to capture Troy (EM).
Trelawney, Sibyll Patricia

Divination professor at Hogwarts, hired by Dumbledore in 1979 after making a prophecy about Harry Potter and Voldemort. She was sacked during the 1995-1996 school year by Umbridge, but reinstated at the end of the year (PA, GF, OP). (More...)
Tremlett,
Donaghan
(b. 1972)
Bass player with the popular wizarding band The Weird Sisters, and a big Kenmare Kestrels supporter (fw94). According to the Daily Prophet, he was married in the fall of 1995 (OP14).
Tremlett was Wizard of the Month on JKR's website for July, 2004 (JKR).
Trimble, Quentin
Author of The Dark Forces: A Guide to Self Protection (PS5) .
"Tremble" = English "to shake, as with fear."
Troy
Irish Chaser, one third of the famous "Troy, Mullet, and Moran" (GF8). See also Troy (city).
"tufty-haired man"
Delivered the eulogy at Dumbledore's funeral (HBP30), and married Bill and Fleur (DH8).
Tugwood,
Sacharissa
(1874 - 1966)
A witch who invented some of the earliest Beautifying Potions and discovered the pimple-curing properties of Bubotuber Pus. The words on her gravestone read, 'Thanks to Sacharissa Tugwood, the world is a more beautiful place' (fw68).
"saccharine" = English for overly sweet.
Turpin, Lisa
(b. circa 1980)
Ravenclaw, 1991 - 1998. A girl who was sorted along with Harry’s class, just before Ron (PS7).
Twiddle,
Mallory
Mallory Twiddle wrote a letter to the Daily Prophet, complaining that Gringotts was using Sphinxes to guard its high security vaults. Apparently, Twiddle had encountered one of these guardians and had spent a frustrating hour trying to figure out its riddles. Eventually, the Sphinx chased him out of the bank (DP).
Twilfitt 
Presumably the co-owner or co-founder of Twilfitt and Tatting's, a wizarding dress shop (HBP6).
Twonk,
Norvel
(1888 - 1957)
A hero who was killed when he saved a Muggle child from a manticore.
Twycross,
Wilkie 
Apparition Instructor from the Ministry of Magic who earned some rather unpleasant nicknames, most starting with the letter D. Twycross is oddly colorless. He is thin and wispy, almost as if a breath of wind could blow him away (HBP18).
