Much to the delight of her fans across the world, "Harry Potter" author J.K. Rowling released more information regarding the boy wizards family.

Rowling relaunched her Pottermore website and published a new essay simply titled, "The Potter Family." In the essay, Rowling revealed the full family history of the Potters.

"The Potter family is a very old one, but it was never (until the birth of Harry James Potter) at the very forefront of wizarding history, contenting itself with a solid and comfortable existence in the backwaters," the essay began.

The Potter family was traced all the way back to the 12th century and started with a wizard named Linfred of Stinchcombe, who had seven children and was described as "a locally well-beloved and eccentric man."

"Linfred was a vague and absent-minded fellow whose Muggle neighbours often called upon his medicinal services. None of them realised that Linfred's wonderful cures for pox and ague were magical; they all thought him a harmless and lovable old chap, pottering about in his garden with all his funny plants," Rowling wrote.

Potter fans then learned that Linfred's eldest son, Hardwin, married Iolanthe Peverell, who was the granddaughter of Ignotus Peverell. Peverell was one of the three brothers who came into the possession of the three Deathly Hallows, magical devices that together make the owner the master of death. The Deathly Hallows were at the center of the final "Harry Potter" book.

"In the absence of male heirs, she, the eldest of her generation, had inherited her grandfather's invisibility cloak. It was, Iolanthe explained to Hardwin, a tradition in her family that the possession of this cloak remained a secret, and her new husband respected her wishes. From this time on, the cloak was handed down to the eldest in each new generation," wrote the "Harry Potter and the Deathly Hallows" author.

Pottermore also announced Tuesday that the Pottermore site was redesigned and now allows readers to consume the content in a different way from when it was launched in 2012. For the first time, Pottermore announced it was also mobile friendly, reported USA Today.

Next year, the J.K. Rowling wrote film based "Fantastic Beasts and Where to Find Them" based off her book of the same name will arrive in theatres on Nov. 18, 2016. "Fantastic Beasts and Where to Find Them," stars Eddie Redmayne, Colin Farrell, Katherine Waterston, Ezra Miller and Alison Sudol.
