Members have been notable as bankers in the City of London, notably as partners in the London bank Fuller, Banbury, Nix & Co, and as large estate owners in Crawley and public officials in Sussex, where John Ashburner Nix served as High Sheriff in 1911.

[1] The family is descended from the leather cutter John Parfitt Nix (died 1802) of Tower Dock in the City of London.

In 1904, the estate went to their son John Ashburner Nix, who served as High Sheriff of Sussex in 1911[6] and who died in 1927.

The estate then passed to his brother Charles George Ashburner Nix who, on the outbreak of the Second World War in 1939, put it up for auction.

The latter's son is Alexander James Ashburner Nix, a long-time director of SCL Group and former CEO of Cambridge Analytica, who is married to Olympia Paus, one of the heirs to the Norwegian shipping company Wilh.
