The Ashkinazi vs. Sephardim Jew issue is a big topic. And it is a very big deal in Israel. I understand how you feel, but at the same time, I seriously doubt that there were blond hair, blue eyed, people running around in the Middle East thousands of years ago. Maybe? I don't know? But it does not seem likely.
Possibly when Esau went North, he gave birth to the Ashkinazim?
Doubtful. One, Esau's descendants were not Jewish. And they went to (more or less) Syria.
And there are plenty of Jews of all descriptions. King David, notably, had bright red hair and a red beard.
The exact descriptor of Jewish people would be (as described by Hashem Himself in the Torah) -- "a mixed multitude."
Undoubtedly many people went (and slaves taken) to Eqypt, from far afield, and became Jews either by conversion or mixed marriages (which were just fine prior to Mt. Sinai).
But eventually, yes, we did merge into one people. All Ashenazi are genetically 5th cousins to one another. Our closest genetic relatives are the Sephadrim and Mizrahim, followed by the Samaritans (who, yes, still exist), Druze, and local Arab populations (who were probably Jewish at one point, and forced to convert first to Nazarine, then muslim).
