The origins of the Rambo family in the vicinity of Gothenburg seem to be pretty well established - Wikipedia mentions a preserved letter home to a sister of Peter Gunnarsson - and I have seen somewhere that there is also DNA evidence.
However, the alternate theory proposed by Ormond Rambo in 1948, suggesting an origin in the village of Rambo in what later became Degerfors parish, in the far north of Sweden still hangs around. It is, for example, mentioned in Swedish Wikipedia. Of course it is also represented in WikiTree, in the shape of an invented father, Gunnar Mattsson Rambo and his father Matt Rambo.
Is there anywhere a published refutal of this theory?
