Alexander in Wikipedia

Etymologically, the name is derived from Αλέξανδρος Aléxandros, which is a compound of the Greek verb ἀλέξω (alexō) "protector of men", "god", "to hold off" and the noun ἀνδρός (andros), genitive of ἀνήρ (anēr) "man". It is an example of the widespread motif of Greek (or Indo-European more generally) names expressing "battle-prowess", in this case the ability to withstand or push back an enemy battle line. The earliest attested record of the name is the Mycenaean Greek of the feminine Alexandra, written in Linear B.[1][2][3] The name was one of the titles ("epithets") given to the Greek goddess Hera and as such is usually taken to mean "one who comes to save warriors". In the Iliad, the character Paris is known also as Alexander. The name's popularity was spread throughout the Greek world by the military conquests of King Alexander III, commonly known as "Alexander the Great". Most later Alexanders in various countries were directly or indirectly named for him...
