Task: Question Answering
Input (English): Passage: The history of Gilwell Park can be traced to 1407, when John Crow owned Gyldiefords, the land that would eventually become Gilwell Park. Between 1407 and 1422, Crow sold the land to Richard Rolfe, and the area became known as Gillrolfes, "Gill" being Old English for glen. Following Rolfe's death in 1422, different sections of the property came to be called "Great Gilwell" and "Little Gilwell". The two areas were named after the Old English "wella", or spring. A farmhouse has stood at Gilwell Farm ever since.
Around this time, an adjoining 5.6 hectares (14 acres) property was purchased by Richard Osborne. In 1442, he built a large dwelling called Osborne Hall, which stood for 300 years. Legend has it that in the early 16th century, King Henry VIII owned the land and built a hunting lodge for his son Edward. Around 1736 the highwayman Dick Turpin began using Gilwell's forests to conceal himself and for ambushing travellers and freight along roads leading into London.In 1754, William Skrimshire purchased Great Gilwell, Little Gilwell, and half of Osborne's estate, including Osborne Hall. Skrimshire demolished Osborne Hall and built a new residence, which he also called Osborne Hall. That building is now called the White House. Timbers in the White House can be dated to this time, but not to any previous era. Leonard Tresilian (?–1792) bought the estate in 1771 and expanded the land holdings and size of the residence.
Tresilian's first wife, Margaret Holland, died young after bearing three daughters. He then married Elizabeth Fawson. Desiring that Gilwell pass on to his eldest daughter, also named Margaret (1750 – c.1844), Tresilian drew up a detailed prenuptial agreement with Fawson's father. By the time of Tresilian's death in 1792, the younger Margaret had married William Bassett Chinnery (1766–1834), the elder brother of the painter George Chinnery. 
Question: What is the name of the person that Leonard Tresilian wanted to leave his estate to?
Output (English): Margaret.
