Speaking of migration of early peoples, I was visiting the Egyptian section at the Houston Museum of Natural History. One of the Egyptian mummies on display had been unwrapped enough to show the man’s face. He was in an amazing state of preservation for being 2,000 years old (period of the Greek Ptolemic rule) and he had red hair and a beard. The museum curator told me that the guy was European and not Egyptian. The curator said that details of his wrapping indicated that he belonged to the middle class and that he was possibly a wealthy merchant. The ancients got around more than we usually think.
This person could have been Greek Ptolemaic also. The Ptolemies were Greek.
He also could’ve been a Galatian Celt from not too far away modern Turkey.
King David of Israel is reported to have had red hair also.
Some of the pharaohs' mummies appear to have red hair. This could be a fading or leaching of color due to age and dehydration, or it could be due to the use of henna (to maintain their hair color as they aged; most Egyptians shaved their heads and wore wigs, to avoid micro-livestock), or it could be they really did have red hair. :').
