Euphemia Potter

Mrs. Potter was pure-blood witch. She was married to Mr. Potter, with whom she had one son, James. She was the paternal grandmother of Harry Potter.

Biography
Mrs. Potter and her husband did not become parents until later in their lives when she gave birth to her son James on March 27, 1960. As such, James was an only child, and was doted on quite a lot.

When James's friend, Sirius Black, ran away from home at age sixteen, he found refuge in the Potter household. Mrs. Potter and her husband came to regard Sirius as something of a second son. After Sirius moved into his own flat, he kept in touch with the Potters, and was always welcome to have lunch with them on Sunday.



Mrs. Potter and her husband both succumbed to a fatal wizarding illness. They were elderly at the time, suggesting they might have contracted dragon pox, which is known to be especially dangerous for older wizards.

Their deaths occurred at some point between when they took in Sirius and the night of October 31, 1981. On that fateful Halloween, James and his wife Lily were murdered by Lord Voldemort, and their son Harry was sent to live with only surviving relatives.

In all likelihood, Mrs. Potter never got a chance to meet her grandson, but she was probably among the relatives who Harry saw when he looked into the Mirror of Erised in 1991.

Behind the scenes

 * The Charlus Potter and Dorea Black who appeared on the Black family tree have been speculated to be James' parents. The couple had one child, a son whose name has not been revealed. If Dorea was in fact James's mother, she would have been forty when he was born, which seems to align with J. K. Rowling's revelation about the age of James' parents. However, Dorea died at fifty-seven, which conflicts with Rowling's statement that James' mother was "old in wizarding terms" when she died . Also, when James was young, he stated that his father was in Gryffindor and he didn't mention his mother, which might be another hint, as almost all Blacks have been Slytherins.
