To find the origin of Sinvani you'll need to go back to the Bible (The Old Testament). As you probably know the land of Israel was spilt into 12 regions or tribes. These were the sons of Jacob and counted Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph and Benjamin. When it came to the time to rebuild the Temple of Jerusalem, King Solomon called upon the family's of the 12 tribes for help.
Senaah [Sin-Wa'] was a family from the tribe of Benjamin, they were Benjamite's. This can be found in the Bible under Ezra
2:35 and Nehemiah
7:38.
What's shown on the chart below is only my part of the Sinvani family.
The base of this family is in Tel-Aviv, Israel. More specifically Givatayim.The family is spread out all over Israel and Europe. All the way from the Golan Heights, to Afula, the Negev and Tel-Aviv.
