Roger de Busli at the time of the Domesday (1086) was the key landowner of the Marnham manor as well as beyond. From this, William de Kewles became lord of these manors, and from this they passed to the Chaworths. Elizabeth, the daughter and heiress of Sir George Chaworth, carried the holdings through marriage to Sir William Cope. By 1853 Earl Brownlow was the principal owner and lord of the manor of Marnham.

Skegby Manor was a 285-acre (115 ha) farm. It was held by Charles Francis Wade in the mid 1800s. Their son Richard Wade became a partner in the Sharpe & Wade solicitor firm based in Market Deeping for many years, and run by several generations of the Wade family. He was also Lord of the Manor in Skegby in 1927. Hugh Wade was one of Richard's sons, and was a noted 1920s-40s musician and writer.

In 1835, White's Directory reported three farm houses and three cottages in Skegby.

There is only one listed residence in the area, Skegby Manor. It is listed at Grade II, and dates from the 18th century. Its pigeoncote auxiliary building is also listed.
