Latinos usually only score less than 3% jewish so why is it always talked about?

[Annie999]

1- Jewiness in latins is not talked about.

2- 3% is not necessarily noise. It might be a misread but if somene score 3% jew they might have true jew blood or from a region nearby. Its also on you to figure out what is noise or not. For example I score 1% native american and I know its real because its read by most genetic tests even GEDmatch. Now, if you score something out of the blue, that can’t be confirmed anywhere else then it’s probably noise or a misread.

3- (to Tenma de Pegasus) one thing is the origin of a lastname and another the DNA the people actually carry. Those names might have been wore by jewish people so many generations ago that by now the blood got super diluted.

I saw some Mexicans score 10%+ Sephardic on FTDNA's myOrigins test before

Especially some mexicans from Nuevo León and antioquian colombians that % is not totally exotic.

But it is, its always talked. Yesterday, my professor was saying that all names like Coelho, Bezerra, Ribeiro and Pinheiro were jew surnames, Im curious about it. These names are very common in Northern Northeast Brazil, I would like to know if its common in the rest of Brazil, Portugal and Minas Gerais or if they really are only common on this "small" part of Brazil.

that's a common mistake, they are not jewish, they are iberian/portuguese. Surnames didn't exist until the middle ages. Jewish people when converting to Catholicism (great part of them forcefully) adopt cristãos velhos surnames, or completely change the exiting ones.

People who have those surnames could or could not have jewish ancestry. For you to know you MUST do you genealogy. other wise is just a guess.

Side note: being descendant of jewish people is different from being jewish/jew.
