Actually it is the opposite,
Alexandros is the masculine form of
Alexandra. In Greek mythology,
Alexandra was a major goddess of the Mycenaean times in Lakonia region (Sparta,
Arcadia, etc.), worshipped greatly in Amyclas and Leuctra where the biggest of her temples were.
She often was represented holding a lyre. In later times she was often identified with
Kassandra, daughter of Priamos of
Troy.
The name compounds from the verb "Alexo", here used as "protecting" rather than "defending" and the noun "
Andras", meaning man. So actually the meaning of the name is "protector of men".
