The name Rambo was likely derived from a shortened form of Ramberget (a hill on the Hisingen island in Gothenburg, where Peter Gunnarsson was born) plus 'bo' (meaning 'resident of'). These apples, in turn, were named for Peter Gunnarsson Rambo who sailed from Sweden to America in the 1640s, and soon the name would flourish in New Sweden. Morrell says that in choosing the name Rambo he was inspired by 'the sound of force' in the name of Rambo apples, which he encountered in Pennsylvania.
