What is "ughill"

Ughill is a small rural hamlet within the City of Sheffield in Bradfield Parish in England. It is located eight km west-northwest of the city centre. It stands in a lofty position at 280 metres (918 feet) above sea level on a ridge between Bradfield Dale and the valley of the Ughill Brook. It has traditionally been a farming community but there was some mining in the area in the late 19th and 20th century. Ughill Hall was the scene of an infamous murder in September 1986. The hamlet falls within the Stannington ward of the City.
