The name Rambo was most likely derived from Peter Gunnarsson's Swedish home on Ramberget (or "Raven Mountain") on the island of Hisingen, which today is part of Gothenburg, but in Gunnarsson's time was mostly farmland. One translation of "bo" from Swedish to English is "resident." The Rambo is very similar in traits, such as size, shape, and coloring, to several French apples called Rambour. There is no known explanation for the similarity of the names.
