Why does my brother have those Slavic ancestry and I don't? We're Spanish; the only foreigner in the family is my French great-grandfather.

I think many of you know this, but I’m Spanish and I have a great-grandfather from northern France, near Belgium. My question is: is that percentage of Jewish ancestry normal for a Spaniard, or is it simply a mistake? It’s just a question, as I’m no expert. I know that where I’m from there are traces of Jewish communities – a Jewish cemetery was even found – but they’re usually Sephardic Jews.
