understand that accepting that "Czarnecki" may have been "Czarnegaje" and, before that, "Sotosnegros" may be hard; but I'm not just pulling these theories out of my head and/or my butt.
Oh but you are, and there's the rub! ;-)
You disregard the etymology and history of both Spanish and Polish surnames completely. You have been told when Polish surnames started to emerge; you have been told where the surname Czarnecki comes from; and you have been reminded that Polish Jews only started taking on surnames approx. 200 years ago. Your possibly Jewish relatives could have been called Czarnecki for a number of reasons, but definitely not because they were descended from Sephardic Spanish Jews.
The Spanish and others weren't as interested in having a "Museum Of An Extinct Race" during the Inquisition and Crusades.
I can understand that, but they also did not have the organisation and logistics back then for a full-blown document-destroying operation. Things were a lot more hit-and-miss, and people or documents would slip through the net. That's all I've been saying all this time.
I'm really curious how far this thread can go before someone's brain explodes ;-)
Anyway, we can't be anti-Semitic towards a baptised Catholic who attended mass on a regular basis for years.
Spot on. And frankly, we've all been quite pleasant to you all this while and it's not us doing the name-calling. I have absolutely nothing against you as a person. I am even trying to have a relatively serious discussion with you on one of the wilder claims that I have ever come across.
