She is described by the Sorting Hat as "good Hufflepuff", or "sweet Hufflepuff, from valley broad". The Sorting Hat's reference to "valley broad" may be a reference to Wales or the Welsh valleys.
Helga Hufflepuff was one of the four Founders of Hogwarts School of Witchcraft and Wizardry. She was a friend of Rowena Ravenclaw. Hufflepuff helped to build the school, and admitted students into her House that were unafraid of hard work. While the other Founders took students based on either ambition, bravery, or intelligence, Helga Hufflepuff took the rest, treating them all equally and teaching them all she knew. She brought people from different backgrounds together to help in the building of the school, and was known for her charming ways.
Helga Hufflepuff had a gift for food-related Charms, and her recipes are still used as the basis for many Hogwarts feasts. Helga Hufflepuff also arranged for the House-elf contingent to work in the kitchens, giving them somewhere safe to work where they would not be mistreated or abused.
 Personality and traits
Hufflepuff favoured loyalty, honesty, fair play, and hard work. Members of her Hogwarts House usually display at least one of these traits in varying degrees. Cedric Diggory, the deceased Triwizard Tournament Champion, was one of the students who appeared to embody all four. Additionally, Hufflepuff was renowned for her compassionate nature; she took in the House Elves to work in Hogwarts Kitchen where they could work in peace and safety and while the other founders were careful in selection of students, Hufflepuff took in the rest.
 Magical abilities and skills
- Magical device inventor: Hufflepuff created a cup which, according to descendant Hepzibah Smith, had magical powers.
- Charms: Hufflepuff was skilled with cooking charms, as many of her recipes are still used in Hogwarts.
One relic of Hufflepuff's, a small golden cup, had been passed down to her distant descendant Hepzibah Smith. Smith said the cup was supposed to have some magical powers, many of which she had not tested. The Cup was stolen from Smith by Tom Marvolo Riddle, who changed it into a Horcrux. The Cup was destroyed by Hermione Granger with a Basilisk fang during the Battle of Hogwarts in 1998.
- The name Helga is from Helge, from Old Norse heilagr, meaning "prosperous" or "brave." Their symbol is the badger, a large mammal related to the weasels with distinctive white stripes on its head. In Celtic mythology, a badger was a guide. The badger also can symbolize a tendency to be hard-working, strong and tenacious (sticking to something and not giving up). Hufflepuffs are known for loyalty and hard work.
- Hufflepuff could mean "huff and puff", or blustery. "Huff" also means to breathe; "Puff" is a Medieval term for pastry.
 Additional Canon
 J. K. Rowling's Official Website
- Helga Hufflepuff was the May 2007 "Wizard of the Month" on J. K. Rowling's website. Both the famous wizard card and the illustration on Rowling's website depict her as a plump woman with red hair.
 Other Stuff
- It is theorized that Zacharias Smith is related to Hepzibah Smith and thus is a descendant of Helga Hufflepuff. Although Smith is obviously a very common last name, both Zacharias and Hepzibah are uncommon names of Hebrew origin. It seems unlikely that the two first names are a coincidence. Should Zacharias be truly a descendant of Hufflepuff, this would be an odd irony, as he lacks the loyalty and fair play that Hufflepuff's house commands, despite being in her house. It's possible that Zacharias was only put in Hufflepuff because he lacked the qualities needed for the other houses and going by one of the Sorting Hat's songs, Hufflepuff did take those at Hogwarts who did not meet the needs of the other houses.
