One piece of information about the origin of shepherd was interesting:
Source: Online Etymology Dictonary
Old English sceaphierde, from sceap "sheep" (see sheep) + hierde "herder," from heord "a herd" (see herd (n.)). Cf. Middle Low German, Middle Dutch schaphirde , Middle High German schafhirte , German dialectal Schafhirt .
Shepherds customarily were buried with a tuft of wool in hand, to prove on Doomsday their occupation and be excused for often missing Sunday church.
Watch out, they may be after your hair on the next shepherding call
