His younger brother Charles Godfrey Mundy is the direct patrilineal ancestor of the Massingberd-Mundy family, who had formerly held the manor of South Ormsby.

As such, he was also a direct descendant of the Plantagenet Kings preceding Edward III, as well as William the Conqueror, the Dukes of Normandy and of Alfred the Great.

In 1825 Mundy had new streets and properties constructed on the site of King's Mead Priory on the west side of Derby.

Whilst this work was being undertaken a coffin was discovered containing the bones of a small woman.

They had five children, one son- William Mundy and four daughters- Marian, Laura (died 1 September 1842 in London[2]), Emily and Constance, who made the notable marriage to William Henry Fox Talbot in 1832.
