You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The Brownlow family, a dynasty of lawyers, began accumulating land in the Belton area from approximately 1598. In 1609 they acquired the reversion of the manor of Belton itself from the Pakenham family, who finally sold the manor house to Sir John Brownlow I in 1619. The old house was situated near the church in the garden of the present house and remained largely unoccupied, since the family preferred their other houses elsewhere. John Brownlow had married an heiress but was childless. He became attached to two of his more distant blood relations: a great-nephew, also called John Brownlow, and a great-niece, Alice Sherard. The two cousins married each other in 1676 when both were aged 16; three years later, the couple inherited the Brownlow estates from their great-uncle together with an income of £9,000 per annum (about £1.35 million in present-day terms) and £20,000 in cash (equivalent to about £3.01 million now). They immediately bought a town house in the newly fashionable Southampton Square in Bloomsbury, and decided to build a new country house at Belton.Work on the new house began in 1685. The architect thought to have been responsible for the initial design is William Winde, although the house has also been attributed to Sir Christopher Wren, while others believe the design to be so similar to Roger Pratt's Clarendon House, London, that it could have been the work of any talented draughtsman. The assumption popular today, that Winde was the architect, is based on the stylistic similarity between Belton and Coombe Abbey, which was remodelled by Winde between 1682 and 1685. Further evidence is a letter dated 1690, in which Winde recommends a plasterer who worked at Belton to another of his patrons.
Output:
What are the full names of the couple who inherited the Brownlow estates from their great-uncle?
