Task: Question Answering
Input (English): Passage: The Domesday Book provides the earliest mention of the area, where it is recorded as "Cedde", Celtic for "wood". Local archaeological finds include Bronze Age axes discovered in Cheadle. Evidence of Roman occupation includes coins and jewellery, which were discovered in 1972. The modern-day Cheadle Road was originally known as Street Lane, and may be of Roman origin. A stone cross dedicated to the Anglo-Saxon St Chad, discovered in 1873, indicates Anglo-Saxon activity. The cross was found in an area called "Chad Hill", on the banks of the Micker Brook near its confluence with the River Mersey; this area became "Chedle". Suggestions for the origin of the name include the words cedde, and leigh or leah, in Old English meaning "clearing", forming the modern day "Cheadle". "Hulme" may have been derived from the Danish word for "water meadow" or "island in the fen".According to the Domesday Book in 1086, the modern-day Cheadle and Cheadle Hulme were a single large estate. Valued at £20, it was described as "large and important" and "a wood three leagues [about 9 miles] long and half as broad". One of the earliest owners of the property was the Earl of Chester. It was held by a Gamel, a free Saxon, under Hugh d'Avranches, 1st Earl of Chester, and later became the property of the de Chedle family, who took their name from the land they owned. By June 1294 Geoffrey de Chedle was Lord of the Manor. Geoffrey's descendant Robert (or Roger) died in the early 1320s, leaving the estate to his wife Matilda who held it until her death in 1326. As there were no male heirs the manor, which was now worth £30 per annum, was divided between her daughters, Clemence and Agnes. Clemence inherited the southern half (which would later become the modern-day Cheadle Hulme), and Agnes inherited the northern half, (latterly Cheadle). The two areas became known as "Chedle Holme" and "Chedle Bulkeley" respectively. Shortly afterwards the Chedle Holme estate was divided and the part where Hulme Hall is now situated became known as "Holme", and held by the Vernons. The estates were reunified on the death of the last of the Vernons in 1476.
