Granville is a village in County Tyrone, Northern Ireland, about 2.5 miles (4 km) southwest of Dungannon. Most of the village is within the townland of Derryveen (from Irish Doire Mhín 'smooth oak-grove'), although some of it extends into Cormullagh (from Cor Mullach meaning "round summit"). The name Granville comes from Thomas Knox, 2nd Earl of Ranfurly who named the village after his son, Granville Henry John Knox, who drowned in the River Tamar in St. Budeaux, Plymouth at the age of 16.
