Alexander is built from Greek roots meaning "to defend" and "man," commonly translated as "defender of men." The name has carried that protective sense through millennia of use, from ancient conquerors to modern namesakes, and it tends to suggest someone who shields others rather than merely leads them.
It behooves the astrologer to consider the time in directions of the planets; but in the fixed stars it is not so needful. - William Lilly (1602.-1681.)
