It would be nice to see some sources for this ancestress as it is nearly impossible to research this more without knowing where her name was mentioned and in what context.
The only von Kolbergs that could be related to this Magdalena von Kolberg that I have found in the Swedish Riksarkivet are:
Burchard Löffelholz von Kolberg and Johan Joachim Löffelholz von Kolberg
Mentioned here:

And this is what I found on Wikipedia about that family. Does this belong to the same family or just a family that is from the place called Kolberg?
...”Die Löffelholz von Kolberg (auch: Löffelholz von Colberg) sind eine Patrizierfamilie der Reichsstadt Nürnberg. Die Löffelholz waren ab 1440, mit kurzen Unterbrechungen, bis zum Ende der reichsstädtischen Zeit im Jahre 1806 im „Inneren Rat“ vertreten und gehörten nach dem Tanzstatut zu den „erst zugelassenen“ ratsfähigen Geschlechtern. ”...
Translated:
...”Löffelholz from Kolberg (also: Löffelholz from Colberg) are a patrician family of the imperial city of Nuremberg. Löffelholz were represented in the "Inner Council" from 1440, with short interruptions, until the end of the imperial city period in 1806 and, according to the dance statute, belonged to the "first admitted" sexes eligible for advice.”...
