Isidor

German, Russian and Macedonian form of ISIDORE.

ISIDORE   male   English, French, Georgian, Jewish
From the Greek name Ισιδωρος (Isidoros) which meant "gift of Isis", derived from the name of the Egyptian goddess ISIS combined with Greek δωρον (doron) "gift". Saint Isidore of Seville was a 6th-century archbishop, historian and theologian.

Though it has never been popular in the English-speaking world among Christians, it has historically been a common name for Jews, who have used it as an Americanized form of names such as Isaac, Israel and Isaiah.
ISIS   female   Egyptian Mythology (Hellenized)
Greek form of Egyptian Ist (reconstructed as Iset or Ueset), which possibly meant "the throne". In Egyptian mythology Isis was the goddess of the sky and nature, the wife of Osiris and the mother of Horus. She was originally depicted wearing a throne-shaped headdress, but in later times she was conflated with the goddess Hathor and depicted having the horns of a cow on her head. She was also worshipped by people outside of Egypt, such as the Greeks and Romans.
