Ibrahim Al-Masyhur ibni Almarhum Sultan Abu Bakar Al-Khalil Ibrahim Shah (17 September 1873 – 8 May 1959) was a Malaysian sultan and the 2nd modern sultan of Johor. He was considered "fabulously wealthy." An Anglophile, Ibrahim maintained close ties with the British crown and frequently leveraged his personal relationships with reigning monarchs to advocate for Johor's autonomy and resist the expansionist ambitions of the British Colonial Office. However, he became highly unpopular later in his native land for his opposition to Malayan independence. This led him to spend most of his time away from Johor, travelling extensively in Europe, particularly to Britain.

Captain François Allan Joubert (1889–1942), administrator of the Cape, parliamentarian and farmer. He married Enid Goldman, whose mother was cousin of the diplomat Charles Te Water who was the South African High Commissioner to the United Kingdom from 1929 to 1939.
