Currently we are wrestling with:
The current distribution and probable origin of the 'Lousada' name is Galicia in northwest Spain together with the neighbouring regions of Portugal and Spain (where it becomes 'Losada'). During their time as New Christians there was little to distinguish our ancestors from the many Lousadas and Losadas known in the records. However we have looked at the 1591 Coimbra Inquisition records of Amador de Lousada from Vinhais who is the only Lousada to appear before the Inquisition in a timeframe consistent with the Baruch Lousada presence in Livorno in 1640. He produced the correct number of children to explain all the Baruch Lousadas evident in later records, including a daughter with the correct name to explain the very close link with the Israel Pereira family and a son Fernao who could be the ancestor of the the Den Haag Louzadas. We do know where Amador de Lousada who was born in 1540 was baptized and confirmed, but his name probably means his parents had spent time either in the Portuguese Lousada town or its 2 satellite villages before moving to Vinhais. If our identification of Amador de Lousada is correct, this makes it likely we have found the place where the Lousada name came from! However our hypotheses need testing and refinement.
An obvious avenue of enquiry is to flesh out the Baruch Lousada passage from Portugal to Livorno perhaps via Madrid for there are many clues about that. The Baruch Lousada links with the Levi Montezinos family (ref 107) and the Israel Pereira family (ref 141) point to a Villaflor/Madrid transition and thence to Livorno for the Baruch Lousadas, Venice/Amsterdam for the Israel Pereiras and Antwerp/Livorno/Amsterdam for the Levi Montezinos family.
What was the role of the Lamegos of Rouen and later Bordeaux? They were associated in the early 1600s with Fernando Montezinos of Madrid and thus indirectly with Abraham Israel Pereira and the Baruch Lousadas. Were they related to the Gomez Henriques family from which came the wife (possibly French - she spells her brother's name Isaque) of Aaron Baruh Lousada of Barbados? We know that France figured in the travel of one of the 2 Moses Baruch Lousadas who appeared early in London. The presence of Curiel/Acosta in-laws in Cartegena des Indes, Barbados and Jamaica suggests that the Lamegos of Rouen or Bordeaux may have been a factor in the Baruch Lousada decision to move to Barbados though the transition of the Mercados from Dutch Brazil to Barbados in 1655 was probably more vital. It seems likely that our key ancestor Aaron Lamego was a descendant of the Rouen Lamegos and then from Bordeaux made his way to Jamaica via Martinique or Guadeloupe from where he would have been expelled in 1685 and then perhaps via Barbados or Saint-Domingue to Jamaica. And we have only clues as to how the Rouen Lamegos were related to the Madrid and earlier trading Lamegos and thus we would like to create an improved account of the Lamego family, which reverted to Judaism in France and Jamaica, had been almost at the top rank of Portuguese New Christian merchant families, and the wealth it generated through early participation in the Atlantic trade made the Lamegos key ancestors of the Lousadas, Mocattas, Aguilars, some of the Montefiores and many other Anglo-Jewish families.
Baron Lyon de Symons aka Judah Low Pressburg was a descendant of Simon Pressburg so we propose an earlier Barrow link with the Pressburgs. Sir Barrow Helbert Ellis 1823-87 was given the 'Barrow' name but this probably was not due to the fact that his aunt Tryphena Esther Lyon de Symons married Simon Barrow of Bath in 1808 but may mean Baruch was also a Pressburg family name. The Barrow link to Austria needs to be further clarified, and an early priority is the Jewish marriage records in Livorno. By this means we can clarify the Barrow link to the Dirzstays of Timisoara and Hungary.
Some other Baruch Lousada links are worthy of further examination. The Baruch Lousadas of Tunis go back to Livorno but this like many other aspects of our ancestors' lives in Livorno is not known in detail. There is a close link between the Levi Lousadas and the Baruch Lousadas (ref 149) and though we have made some suggestions the real position remains unresolved. It is of great interest in that though we suggest Baruch in Livorno (the key Barrow ancestor) married a Baruch Lousada we cannot rule out the possibility that the person he married was a Levi Lousada! 'Lumbroso' was the name of a high-placed Jewish family which like the Seniors and the Abravanels performed key economic services for the Spanish Crown (ref 128) and perhaps the Lumbroso Lousadas of Livorno were related to both them and the Baruch Lousadas. And the NY chocolate merchant Jacob Lousada may yet turn out to be part of the third and last wave of emigration of our ancestors from Portugal.
The ancestry of Errol Barrow, first post-independence Prime Minister of Barbados, can perhaps be taken back to the local Baruch Lousadas.
Montefiore ancestry is not certain and a link to the Carvajals of Mexico needs confirmation though in Cordoba to this day there is no doubt about it. In particular was Judah Leon Montefiore - the origin of the family that gave rise to the English Montefiore - Joseph de Leon? For we show that it is unlikely that he was the son of Joseph de Leon as one account has it.
A key Baruch Lousada ancestor was Baron Moses d'Aguilar but his history is plagued by an abundance of inconsistent accounts. Fortunately Abigail Green has noted that an Oxford colleague is writing what we hope will be a definitive biography and we propose to defer to him.
