Bilius

Bilius was an uncle of Ron Weasley and his siblings. He reportedly died twenty-four hours after seeing a Grim.

Family
Bilius' surname and precise relation to the Weasley family is unknown. He was only ever described by his nephews Ron, George, and Fred Weasley as "Uncle Bilius."

It is often presumed that Bilius was the brother of Arthur Weasley, as Arthur was known to have two brothers, neither of whom were ever referred to by name. However, it is still possible that Bilius was a brother or brother-in-law of Arthur's wife, Molly.

Bilius is likely the source of the middle name of one of his nephews: Ronald Bilius Weasley.

Life and death
Bilius never married and presumably had no children. According to his nephews, Fred and George, he was always a joker and was fun to have at weddings and parties. On more than one occasion, he was said to have consumed an entire bottle of Firewhiskey and then run to the dance floor, where he lifted his robes and began to pull bouquets of flowers out of somewhere alarming.

Bilius died twenty-four hours after having seen a Grim sometime in or prior to September 1993. According to his family, however, he went "loopy" toward the end of his life, so whether or not he actually saw the Grim is debatable.
