Ham’s Sin
Noah began to plow the fields, and he planted a vineyard. One day he drank some of the wine, not knowing its strength, he became drunk. Seeing his father lying drunk in his tent, Ham told his brothers about it in a very rude way. His two brothers went into the tent, where they covered their father and put him in his bed without looking at him in his shame. When Noah awoke and found out what had happened, he was angry at his son Ham, saying that Ham’s children should be slaves to the children of his brothers Shem and Japheth.
Shem and His Descendants
Then he prayed that Shem and Japheth have wisdom and beauty, and great social and cultural achievements. Shem became a prophet of G‑d and lived six hundred years, serving G‑d as a priest. In the time of Abraham, who was the ninth generation in direct line of descent from Shem, Shem was famous under the name of Malkitzedek, the “Just King,” who brought offerings to G‑d. He lived to see the eleventh generation of his descendants (Jacob). Together with his worthy great-grandson Eber, he taught and spread faith in G‑d and in His commands in a school which was known as the Academy of Shem and Eber.
During the time of Eber’s son Peleg, the lifespan of human beings dwindled down to about one half of what it was in the former generation.

Nothing was said about Japheth's descendants. I am a evangelical Christian but I love Israel and respect the Jewish people. I realize without Judaism there would be no Christianity. With the little research I have done, I found the word "Ashkenaz" is Hebrew for Germany, therefore an Ashkenazi Jew is a German Jew? My DNA results show I'm a small % European Jewish, and I believe it is German Jew, Buchtmann was my GrGM's maiden name. I read in one post below that most Europeans were descendants of Shem? Of course people migrate, take wives from other countries, etc., so that makes every country a mix of ethnic groups. What about Japheth, which groups of people do the say descended from him?
Over time, migration has erased all of these demographic boundaries. Ashkenazi Jews migrated from the Middle East. Nobody has stayed put.
In the Torah, the descendants of Japheth spread to Media, Persia, Italy, Germany, France, Greece, and many other island nations. See Radak and Rashi to Genesis 10:2-5.
Did shem live in isreal at the time? What was the land called? Is it true that Egypt had control of cannan
