This chart shows the marriage of Claude Lousada and Maude Spielmann in the context of a complex earlier connection which involves many Ashkenazi families (including the Goldsmids) linking two Sephardic families (with the proviso that note ref 297 makes the suggestion that 'Keyser' is a vernacular version of 'de Caceres' so it may be incorrect to assume that the Keysers were Ashkenasi!). But having found this link, it has particular resonance for Australian Lousadas as it shows Sir Barrow Helbert Ellis (see picture below), after whom Barrow Helbert Ellis Lousada was named. Some reminiscences of the Spielmann and Sebag-Montefiore families can be found in ref 126 (including on p87 a sweeping assessment of the (lack of) cultural aspiration of Claude Lousada!).
The connection shown in the chart was found after we unsuccessfully tried to link Lewis Cohen (aka Judah son of Isaac Cohen ref 132 marriage #20) who married a granddaughter of Simon Barrow and who can therefore be found on the Barrow Family tree, with Adelaide Cohen. However the Descendants of Israel Israel document shows the mother of Adelaide Cohen as Rebecca Floretta Keyser #124 1807-1859, who married a Louis Cohen #970 1799-1882 (as shown on the Ashton Family Tree on ancestry.com), whilst the will of Lewis Cohen (http://synagoguescribes.com/blog/Jewish-will-extracts-18th-19th-century/?value=1017) shows no children and death ~1823. Clearly Lewis Cohen, Barrow relative, is not Louis Cohen, Maude Spielmann's ancestor! A link via the Keysers is shown on geni.com as of 31 Jan 2019 where Rebecca Floretta Keyser is shown as the sister of the great-great-grandfather of Charles Mortimer Keyser who married Marion Irene Lousada #246 the daughter of Claude and Maude; however we have not found a link to Alexander Isaac Keyser the Goldsmid in-law. Levi Barent Cohen was the father-in-law of Sir Moses Montefiore.
A link via the Barrows exists - Joseph Elias Montefiore in this chart was a brother of Eliezer Montefiore who married Judith Joseph Levi who was a cousin of Simon Barrow of Bath; the Barrows in Australia chart shows this marriage. And of course a link via the Mocattas exists as shown in the chart covering the marriage of Claude Lousada's parents. Finally, because all the descendants of Simon Barrow of Barbados are also descendants of Bailah Montefiore, there is a fundamental (Montefiore) link!
Sir Barrow Helbert Ellis (1823-1887) was an Anglo-Indian. He was the son of Samuel Helbert Ellis (formerly Samuel Helbert Israel), a prominent member of the Jewish community in London. His mother Fanny was a sister of Samuel and Tryphena Lyon de Symons and hence Sir Barrow Helbert Ellis was a cousin of Tryphena Jael Louisa Barrow, mother of Edward Charles Lousada who happened to be in England in the year of Sir Barrow's death and may have attended the funeral. His forename Barrow is one of the clues which prompted us to reflect upon the Barrow Ashkenasi ancestry. He can hardly have been given this name solely because his aunt Tryphena married Simon Barrow of Bath; the name must have been in the family earlier than that. We suggest that the namesake was Baruch, father of Simon Barrow of Barbados just as the namesake of Samuel Lyon de Symons - 2nd husband of Bella Barrow - was Samuel Michael Lazarus Pressburg an ancestor of Baron Lyon de Symons.
Sir Barrow Helbert Ellis was educated at University College School, he matriculated at London University in 1839 and went to Haileybury. There he distinguished himself in all branches of study, and left in 1843 as senior student to enter the civil service of Bombay. His first appointment in India was as third assistant-collector and magistrate of Ratnagiri; he was promoted to the post of second assistant in 1847, and in 1848 was made commissioner for investigating certain claims upon the Nizam's government. In 1851 he arrived in Sindh as assistant-commissioner, and from 1855 to 1857 was in charge of the offices of chief commissioner during the absence in England of Sir Bartle Frere. He was made special commissioner for jagirs or alienated lands in the province before leaving Sindh in 1858. In 1859 he was collector and magistrate at Broach, and, after serving as chief secretary of the Bombay government, was nominated an additional member in 1862 and an ordinary member in 1865 of the Bombay council. Five years later he was promoted to the viceroy's council. In 1875 he returned to England, and was made not only KCSI but a member of the Indian council in London. He retired in due course from the council, on whose deliberations he exerted much influence, in 1885. Ellis died at Evian-les-Bains on 20 June 1887 and was buried in the Jewish cemetery at Willesden, Middlesex. He was an excellent revenue and settlement officer — 'one of the ablest revenue officers of the Bombay Presidency,' in the words of Sir George Birdwood. While at Bombay Ellis was exceptionally popular with all classes of native Indians. He was at all times accessible to them, both in India and England, and the native newspapers eulogised him unstintingly at the time of his death. He left a sum in trust for the poor of Ratnajiri, his first official charge. He was not married. On his retirement from India he took a prominent part in the affairs of the Jewish community of London, being vice-president of the Anglo-Jewish Association and of the Jews' College, where a portrait has been placed. Ellis published a report on education in Sindh (Bombay, 1856), and edited George Stack's `Dictionary of Sindhi and English' (Bombay, 1855). He was an active member of the Royal Asiatic Society which he joined in 1876. He founded a prize in Bombay University, and a scholarship there was established in his honour in 1875.
