Wizards, Witches and Beings: R
Rabnott, Modesty
Tried to stop Barberus Bragge from his barbaric treatment of a Golden Snidget, only to be fined 10 Galleons for her trouble (a huge amount of money in those days). The Modesty Rabnott Golden Snidget Preserve in Somerset is named after her. Modesty owned a Hippogriff, but the house she owned had to be sold to pay the huge fine and she was forced to go live with her sister Prudence in Aberdeen (QA4).
Rackharrow,
Urquhart 
(1612 - 1697)
Inventor of the Entrail-expelling Curse; a portrait of this nasty-looking wizard hung in the Dai Llewellyn Ward in St. Mungo's (OP22).
Radford,
Mnemone

(1562 - 1649)
Mnemone was the first Ministry of Magic Obliviator due to her creation of Memory Modifying Charms.
Radford was J.K. Rowling's
Wizard of the Month for February 2007 (JKR).
Name meaning: her name seems to be a combination of Mneme (who was
the Ancient Greek Muse of Memory) and another Greek name, Anemone (a flower).
Radulf 
(1100s)
A Yorkshire blacksmith who was roped into playing Catcher for the local team in their match with Ilkley in the 1100s. Radulf took a "Blooder" to the head in that game (QA3).
Rapier
Fred (or perhaps George) Weasley’s code name when he appears on "Potterwatch," though Lee Jordan initially tried to call him ‘Rodent’ instead (DH22).
Rastrick,
Xavier
(1750 - 1836)
Flamboyant wizarding tap-dancer; he vanished unexpectedly in the midst of a performance in Painswick and was never seen again (fw).
Ravenclaw,
Helena
(c.1000 A.D.)
More commonly known as "The Grey Lady," the Ravenclaw ghost.
Harry and Ron first encounter this tall ghost as she glided past in the corridor while out looking for the Mirror of Erised (PS12). Harry eventually discovers that The Grey Lady is Helena, the daughter of Hogwarts founder Rowena Ravenclaw. Helena stole her mother's diadem and ran off to Albania. Her mother became deathly ill soon after and sent Helena's estranged fiance to find her and bring her back. When she refused, the baron (now The Bloody Baron) killed her and committed suicide in remorse. (DH31).
Before Deathly Hallows was published, Rowling told a fan named Nina Young that the Grey Lady is "a highly intellectual young lady" and a woman with strong scholarly or literary interests. "She never found true love as she never found a man up to her standards."
Ravenclaw,
Rowena
(c.1000)
One of the four founders of Hogwarts. (More ...)
Riddle, Tom Marvolo
(1926 - 1998)
Slytherin, 1938-1945.
Wizard who, after leaving Hogwarts in 1945, became Lord
Voldemort. (More...)
Ridgebit,
Harvey 
(1881 - 1973)
A Dragonologist famous for catching a Peruvian Vipertooth and establishing a Romanian dragon sanctuary (JKR). Charlie Weasley may work in the dragon sanctuary that Ridgebit founded.
JKR's Wizard of the Month for January, 2007.
Name origins: His name makes it sound like he was destined to be bitten by a Norwegian Ridgeback, perhaps the reason for his bandaged hand?
River
The host of the brilliant, subversive wizarding radio program "Potterwatch," River is actually a code name for Lee Jordan (DH22).
Rivers
Hogwarts student in Harry's year?
This last name appears in the draft of the classlist of Harry's year that Jo displayed during the "Harry Potter and Me" TV interview (HPM). This name cannot be considered canon, however, because the notes on this document conflict in too many places with the stories as they were actually published.
Robards, Gawain
Head of the Auror Office of the Ministry of Magic, replacing Rufus Scrimgeour (HBP15).
Robins, Demelza 

Gryffindor Quidditch team, Chaser (HBP11). A quality Chaser for a Gryffindor team that won the House Cup in 1996-1997 (HBP24), Demelza is "particularly good at dodging Bludgers."
Demelza probably
refers to
Demelza
House, the favorite charity of actor Daniel
Radcliffe.
Rodent
While hosting "Potterwatch," Lee Jordan initially used this code name to refer to Fred Weasley. A quick background conversation, though, revealed that Fred actually wanted to be called Rapier, so to keep the show moving, Lee relented (DH22).
Romulus
On "Potterwatch," this was the code name for Remus Lupin (DH22). For anyone with a knowledge of Muggle history, this wouldn’t have been a hard one to guess, as Romulus – the founder of Rome, according to legend – had a twin named Remus.
Rookwood,
Augustus 
(d. May 2, 1998)
Pockmarked, stooped Death Eater and Ministry wizard working in the Department of Mysteries; friend of Ludo Bagman's father (GF30). Rookwood was turned in to the Ministry of Magic by Igor Karkaroff c. 1981. Escaped from Azkaban during the mass breakout of January 1996. Took part in the Battle of the Department of Mysteries in June, 1996 (OP25, OP35). He fought in the Battle of Hogwarts, killing Fred Weasley (DH32) before finally being leveled himself by Aberforth Dumbledore (DH36).
In first British editions of Harry Potter and the Order of the Phoenix, Rookwood's name is erroneously given as Algernon.
Roper, S.
Hogwarts student in Harry's year?
This last name appears in the draft of the classlist of Harry's year that Jo displayed during the "Harry Potter and Me" TV interview (HPM). This name cannot be considered canon, however, because the notes on this document conflict in too many places with the stories as they were actually published.
Rosier
One of the earliest members of the Death Eaters (as early as c. 1955), along with Nott, Mulciber, and Dolohov (HBP20). Probably related to Evan Rosier.
Rosier, according to medieval demonology texts, is the patron devil of seduction. He tempts humans to fall in love and causes them to act foolishly.
Rosier, Druella
Druella married a great-grandson of Phineas Nigellus Black. Children: Bellatrix (Black) Lestrange, Andromeda (Black) Tonks, and Narcissa (Black) Malfoy (BFT). See also: Black family.
Rosier, Evan 
(b. late 1950s or early 1960s - c. 1980)
Slytherin (GF27).
Attended Hogwarts with Severus Snape (GF27),
so he was probably a child of the elder Rosier (see).
Killed along with Wilkes by Aurors "the
year before Voldemort fell" (c. 1980)
(GF27, GF30).
Rosier, according to medieval demonology texts, is the patron devil of seduction. He tempts humans to fall in love and causes them to act foolishly.
Rosmerta,
Madam 
Madam Rosmerta is the proprietor of the Three Broomsticks in Hogsmeade. (More...)
'Rosmerta' = a Celtic goddess of fertility and wealth. Rowling chose the name because it means "good purveyor." (JKR)
Rowle, Thorfinn 
A large, blonde Death Eater who broke into Hogwarts the night Albus Dumbledore was killed (HBP28). He showed up again later that summer, following Harry, Ron, and Hermione into a café along with Antonin Dolohov; after failing to capture Harry that day, he was punished severely by Voldemort (DH9).
Royal
On "Potterwatch," this was the code name for Kingsley Shacklebolt (DH22).
Rufford, Grugwyn
Disgruntled member of the National Welsh Gobstones Team, who complained to the Daily Prophet because they didn't cover the Welsh victory over Hungary. The editor responded that this was because people thought Gobstones was "deeply boring" (DP).
Runcorn
Hogwarts student in Harry's year?
This last name appears in the draft of the classlist of Harry's year that Jo displayed during the "Harry Potter and Me" TV interview (HPM). This name cannot be considered canon, however, because the notes on this document conflict in too many places with the stories as they were actually published.
Runcorn, Albert 
A tall, bearded wizard who works for the Ministry of Magic. He unwittingly played a part in Harry, Ron, and Hermione’s infiltration of the Ministry when Hermione gave him a Nosebleed Nougat, convinced him to go home, and took some of his hairs to add to Polyjuice Potion for Harry (DH12). While impersonating Runcorn, Harry discovered that he was someone Mr. Weasley deeply disliked who was informing on “Mudbloods” to the Ministry (DH13). Runcorn turned in Dirk Cresswell, the Ministry's Head Goblin Liaison, who escaped imprisonment but was later killed by Death Eaters (DH15, 22).
Ryan, Barry
Keeper for the Irish National Side (GF8). Made a spectacular save against Poland's top Chaser, Ladislaw in 1995 (OP19).
