The Abudientes made their extensive fortune from the sugar cane, worked by the unfree labour of enslaved Africans and European indentured servants on their plantations.

[1] His brothers-in-law, married to the aforementioned sisters, included; Simson da Costa Athias (who was an investor on the London stock market), Jacob Lobatto and Moses Carriao de Paiba.

The Hats government in Sweden (controlled by pro-Jacobite freemasons) had invited Sephardic Jews in Britain to join the Swedish East India Company, which also included a number of Scotsmen who were members of Masonic Lodges.

The British government then encouraged pro-Hanoverian freemasons Joseph Salvador and Sampson Gideon to entice influential Scots to join the East India Company to undermine the Swedish-based Jacobite masonry.

[8] Sampson Gideon was able to successfully navigate the South Sea Company bubble, which bankrupted many prominent people in Britain (indeed, James Picciotto in his Sketches of Anglo-Jewish History states that no "Hebrew" name is to be found on the list of insolvencies).

[11] This stabilised the situation and by the time that the Jacobite advance into England had halted before it reached London and the momentum switched as they were now in retreat back to Scotland, Gideon had doubled his wealth.

The Whiggish political class under the Pelhams and the Hanoverian monarchy reigned supreme and owed a significant part of their position to Gideon's calm actions and financial activities.

Gideon was ambitious and wished to found a dynasty with vast landed estate interests in England (as the Rothschild family would go on to successfully achieve in the next century).

As Sampson Gideon and Joseph Salvador had provided a useful service to the Hanoverian-Whiggish regime against their rivals, they were confident enough to lobby Henry Pelham to introduce the Jewish Naturalisation Act 1753 to Parliament.

In 2005, the Bexley Civic Society restored a memorial to Sampson Gideon, located in the grounds of All Saints Church, Belvedere, and produced a plaque bearing a brief history of his life.

Such was his reputation that the British government resorted both to his wealth and advice to underwrite the national debt, and finance the army during the Jacobite Rebellion of 1745 and the Seven Years' War of 1756–63.
