He was less successful in extending control into Wales. The third son of William the Conqueror, he is commonly referred to as William Rufus ( Rufus being Latin for "the Red"), perhaps because of his ruddy appearance or, more likely, due to having red hair as a child that grew out in later life. William was a figure of complex temperament, capable of both bellicosity and flamboyance. He did not marry nor have children, which-along with contemporary accounts-has led historians to speculate on homosexuality or bisexuality. He died after being hit by an arrow while hunting, under circumstances that remain unclear. Circumstantial evidence in the behaviour of those around him raises strong, but unproven, suspicions of murder. His younger brother Henry I hurriedly succeeded him as king. Historian Frank Barlow observed William was " rumbustious, devil-may-care soldier, without natural dignity or social graces, with no cultivated tastes and little show of conventional religious piety or morality-indeed, according to his critics, addicted to every kind of vice, particularly lust and especially sodomy." On the other hand, he was a wise ruler and victorious general. Barlow noted, "His chivalrous virtues and achievements were all too obvious. He had extended Anglo-Norman rule in Wales, brought Scotland firmly under his lordship, recovered Maine, and kept up the pressure on the Vexin." He had maintained good order and satisfactory justice in England and restored good peace to Normandy. William's exact date of birth is not known, but it was some time between the years 10. He was the third of four sons born to William the Conqueror and Matilda of Flanders, the eldest being Robert Curthose, the second Richard, and the youngest Henry. Richard died around 1075 while hunting in the New Forest. The existence of sisters Adeliza and Matilda is not absolutely certain, but four sisters are more securely attested: William succeeded to the throne of England on his father's death in 1087, but Robert inherited Normandy.
