Task: Question Answering
Input (English): Passage: The sixth William was briefly succeeded by his son Peter, who was followed by his son William. William the seventh's son was the eighth William Davenport, and an inventory of his property made shortly after his death in 1706 shows the gallery and gatehouse of Bramall were still intact. His two eldest sons each inherited the estate but both died young and heirless, so the estate passed to their younger brother Warren Davenport. Warren became part of the clergy, and during his tenure at Bramall set up a school close to the entrance of the estate. The tenth and final William Davenport succeeded his father, Warren at the age of four. Many changes were made to the house during his tenure, including the dismantling of the gatehouse side of the courtyard and the long gallery, the latter of which may have been done because of their being considered unsafe. William had no sons, so the estate passed to Salusbury Pryce Humphreys, the husband of his illegitimate daughter Maria.Humphreys, a Naval captain, had married Maria Davenport in 1810, and lived at Bramall Hall long before he succeeded his father-in-law. He became widely respected in the Stockport area, but following his succession to the estate in 1829, there were disputes from other members of the Davenport family who claimed a right to the property. Edmund Davenport, who claimed ancestry from Thomas Davenport, the third son of Peter, unsuccessfully contested the succession in two different courts; Edmund was eventually imprisoned for failing to pay the legal fees. Humphreys was knighted in 1834 for his services, and in 1838 changed his name to Davenport, in an effort to continue the Davenport line. He moved with Maria to Cheltenham in 1841, most likely because living at Bramall had become expensive or because of health concerns. Salusbury died there four years later and was buried in Leckhampton.Over the next decade the house was likely to have been let, as Maria Davenport preferred to live elsewhere. Her eldest son, William Davenport Davenport married firstly to Camilla Maria Gatt, then secondly to Diana Handley, whom he lived with at Bramall for four years before the estate was passed to him. Maria moved to London where she lived with her youngest son, Charles, and died in 1866. During William's tenure Bramall was regularly visited by members of the public, and the Chapel continued to be used for regular services of worship. However, following his death in 1869, the property was let to Wakefield Christy of Christys & Co Hatting, therefore ending direct involvement from the Davenport family. This occurred because William's son, John, was too young to inherit the estate. John's whereabouts during Christy's seven-year tenure is unknown, though he was shown as a visitor at Bramall in 1871, and in 1874 became the first chairman of the Bramhall School Board. In 1876, shortly before he returned to the house, he was listed as living on Ack Lane in Bramhall.
