He had Austrian connections as the son of Benedikt Moses Worms and Schönche Jeannette Rothschild, brother of Baron Salomon B. de Worms. His maternal grandfather was the founder of the Rothschild banking dynasty. With his other brother Gabriel, Maurice invested in a plantation in Ceylon to grow coffee and tea. His nephew, son of the Baron of Worms, Henry de Worms (1840-1903) was a politician raised to the peerage with the title of Baron of Pirbright, in the County of Surrey in 1895. The Pirbright family also used that VINCTUS NON VICTUS (bound but not conquered) motto, but not that crest.

The candlesticks are lovely and sterling hallmarked for London, 1750. The maker mark is a script ‘SJ’ which is for Simon Jouet, registered in February 1748.
