This article: Until its acceptance by the National Trust, Belton House was always in the ownership of the family of its builder, though the failure of three generations to produce a son and heir caused the ownership to pass sideways and sometimes through the female line. The owners of Belton are buried in the village of Belton's parish church close to the house. Their tombs are collectively one of the most complete sets of family memorials in England—continuous generation to generation for almost 350 years. The earliest Brownlow buried here is the founder of the family fortune the lawyer Richard Brownlow (1555–1638), and one of the most recent is the 6th Baron Brownlow (1899–1978).
