Sephardic Jews DNA results

[Rober_tce]

What this article does not take into account are the Jewish converts who returned to the Iberian Peninsula after the general expulsion of 1492.

According to Joseph Pérez, the total number of converts finally expelled, after the return of someof them, would be around 50,000.

I don't like wikipedia links, but this particular paragraph summarize very well what I mean.


The number of Jews expelled remains a matter of controversy. The figures have ranged between 45,000 and 350,000, although the most recent investigations, according to Joseph Pérez, place it at around 50,000, taking into account the thousands of Jews who, after leaving, returned due to the mistreatment they suffered in some reception places, such as Fez, Morocco.[67] Julio Valdeón, also citing the latest research, places the figure between 70,000 and 100,000, of which between 50,000 and 80,000 would come from the Crown of Castile, although in These numbers do not count those returned.[67]

Other paragraph of Joseph Pérez’s book (Los judíos en España):

“All expenses were borne by those expelled: travel, maintenance, boat freight, rights of passage... They contracted ships at very high prices whose owners later did not fulfill the contract; Other bosses murdered those they were carrying to steal the little they owned. How many Jews left Spain then? The evaluations that have been given vary between 40,000 and 350,000; Bernáldez speaks of 170,000. The most recent works, based on reliable sources, give a total of less than 50,000, taking into account those who returned.
There was a proportion that is difficult to specify. Luis Suárez Fernández has been able to give a list of 177 names, generally heads of families, which implies that the number of individuals is higher. Many of those who had gone to Fez, in view of the poor treatment they were given, preferred to return to Spain and asked the governor of Asilah to baptize them.”

The book is written in spanish. I don’t know if there is an english version.

Sharp thanks!

Nice add to the paper.

Nevertheless this paper shows something different:



Share of Sephardim (conversos) in the current population, Asturias peaks enormously and E-V22 (with 4.44% next to Sicily) also peaks: the highest in Europe. No coincidence imho.

That paper is outdated and based on early/incomplete haplogroup data and flawed methodology. It basically extrapolates all instances of a haplogroup E to denote NW African admixture; all instances of haplogroup J to denote Sephardic admixture; and all instances of haplogroup R1b to denote local Iberian admixture. This was before downstream clade assignments were a thing. None of these proposed admixture ratios are reflected in autosomal findings or modern haplogroup data from any of these regions. NW African admixture averages between 2-5% in the mainland Iberian population and Sephardic admixture is not statistically significant be reflected in regional averages (though there are certainly individual samples that can be found).

The Asturias data, for example, is based on a sample size of 20 and assigns ‘North African’ admixture on the basis of positive calls for E3b and assigns ‘Sephardic’ admixture on the basis of positive calls for haplogroup J2 and G (the glaring flaws in this methodology should be self-evident). I suggest you take this 16 year-old study in its proper context.

I suppose you talks about NA markers as an global iberian average (maybe 4-5%). North African admixture in Iberia reach in some regions 9-10% ad máximum, for example Portugal, corresponding to last papers. Althougth we need more papers with more samples about it in future.

For sephardic origins, it would be more complex, the haplogroups are inssuficient, we must take in consideration haplogroups, autosomal genetics and historic records. To see the global impact in modern iberians don’t make sense, it’s clear that jewish converse population after 1492 was concentred in some regions (as I have said before), so the papers would should take in consideration specific regions according to historic records, even part of sephardic genetic some modern individuals could lose it… the sephardic ancestors and converse lived between 15th and 17th centuries, then they mixed with christian population and the incipient endogamy of precendent centuries was broken, we don’t inherit all markers of our ancestors, and the minoritary markers are the first that we lose through generations.

Having said this, let’s not divert the thread with NA genetics, NA theme is recurrent in Spain, but this thread is dedicated to Sephardim.
