Brian, Here is another theory to the origin of the Starbuck surname origin:
The name Starbuck is Scandinavian and signifies a person of imposing appearance, great or grand bearing.....bokki meaning "vis grandis corpore et animo. Ferguson gives it Starbocki, from Star, great "vir imperiosus." It is not improbable that the family was of Danish origin and settled in England in the days of what is historically known as the Danish Invasion. Patronymica Brittannica says in "O. Norse bokki; means "vir grandis, corpose et animo." Hence Starbocki from Stor, great.
