William Ferrers, 5th Baron Ferrers of Groby
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.
