Isidore

Isidore (/ˈɪzədɔːr/, sometimes spelled Isidor, Isadore, or Isador) is a male given name of Greek origin, derived from Ἰσίδωρος, Isídōros (a compound of Ἶσις, Ísis, and δῶρον, dōron: "gift of [the goddess] Isis").

Similar "gift" names include the Greek "Theodore" ("gift of God"), the Persian "Mithradates" ("gift of Mithras") and Datis ("gift"), and the Hebrew "Matanya" ("gift of YHWH"). The Indo-European "gift" names are ultimately derived from the *PIE root *deh₃-, "to give".
