List of Famous people named William

William Leonard Langer was the chairman of the history department at Harvard University. He was on leave during World War II as head of the Research and Analysis Branch of the Office of Strategic Services. He was a specialist on the diplomacy of the periods 1870–1900 and 1937–1941. He edited many books, including a series on European history, a large-scale reference book, and a university textbook.

William Gordon was a 17th-century landowner and Covenanter. He is remembered as being a correspondent in Samuel Rutherford's Letters and being one of the biographies in John Howie's Scots Worthies. He was regarded as a man of strong religious convictions and piety. In 1664 he was banished for listening to ministers who lacked a government licence, both at his mother's house and in the woods. He arrived at the Battle of Bothwell Bridge after the fighting was over and, hesitating to surrender, was shot.

William Ferrers, 5th Baron Ferrers of Groby (1372–1445) was an English baron in the late middle ages. He was an important figure in Leicestershire society and took part in most of the royal commissions that were held there. He was also active at a national level and earlier in his career he took part in some of the crises in the reigns of both King Richard II and Henry IV. However, he supported the Lancastrian regime under Henry V and acted as a councillor to that King's baby son when the latter inherited the throne at the age of six months. Ferrers was married three times, twice to daughters of the peerage. Because his eldest son died before him, the Ferrers barony descended to his granddaughter's husband. Thus, when William Ferrers died, the Ferrers line, which had begun in England with the Norman conquest, after which they were first granted lands in Leicestershire came to an end.
