Fridwulfa was a giantess and the mother of the Half-giant Rubeus Hagrid, and the giant Grawp. In 1928, Fridwulfa bore a child with Mr Hagrid, but deserted him and her son, Rubeus, when he was three years old. She returned to the Giants, and bore another child, Grawp, by another giant. She died years before the events of the Second Wizarding War.
The reason she deserted Rubeus was because he was "small" in size, and Giants prefer to produce large-sized children. The same disappointment went to her second son, Grawp. For her desertion, Mr Hagrid was heartbroken and Rubeus didn't remember her much except for not being a great mother.

Behind the scenes
- In 1995, when Rita Skeeter published an article on Hagrid's half-giant ancestry, she mentioned Fridwulfa by name, even though no one (aside from Hagrid, who had told her to leave) knew it. It is possible this may have been information that Skeeter somehow picked up while spying in her animagus form as a beetle.
