From Isidoros to Isadore
The story of Isadore
Isidore of Seville was a seventh-century bishop who compiled an encyclopedia of everything then known, and he has been half-jokingly proposed as the patron saint of the internet on that account. The name was also taken up widely by Jewish families in nineteenth-century Europe and America as a secular equivalent for Isaac and Israel, which is why Isadore appears in the American registers in real numbers, peaking around 1900.
Meaning
gift of Isis
From the Greek Isidoros — Isis, the Egyptian goddess whose cult spread across the Hellenistic world, and doron, 'gift'. The compound is transparent and undisputed, and it survived into Christian use because the name was too well established to abandon.
