Origin of the name Simeon

From Συμεων (Symeon), the Old Testament Greek form of the Hebrew name Shim'on (see Simon). In the Old Testament this is the name of the second son of Jacob and Leah and the founder of one of the twelve tribes of Israel. In the New Testament the Greek rendering Σιμων (Simon) is more common, though Συμεων occurs belonging to a man who blessed the newborn Jesus. He is recognized as a saint in most Christian traditions.
This name was also borne by a powerful 10th-century ruler of Bulgaria who expanded the empire to its greatest extent.
