Neheim Havermann origins

When I first started exploring my father's genealogy on the internet, the starting-point location was necessarily Neheim where I was born (the red rectangle in the map). The larger part of Neheim (the blue rectangle to its right) was of course where many of my ancestors lived and died. There are rectangles around nearby Vosswinkel and Hüsten because they occasionally appear in the records.

Around the time FamilySearch showed me that I had ancestors going back to before 1800, I realized that the focus of the earlier Havermann names was Körbecke (at the top of the map, more to the right). In fact, that had me title an early ancestor chart Havermann: Körbecke ... Neheim ... Toronto. It was Körbecke because of course there was a church there. My very recent exploration of Matricula Online allowed me to look at those church records and the Havermann folk lived mostly in Völlingsen, which stumped me at first until I realized it was a shortening of Völlinghausen (to the right of the Möhnesee, a reservoir built 1908-1912).

Today I looked up the Havermann name in Allagen, another place where FamilySearch had long ago suggested they had church records. These Havermann families lived mostly in Niederbergheim, in between Völlinghausen and Allagen (all on the right of the map). So my revised conjectural travel story for Havermann (thus far) is: Niederbergheim ... Völlinghausen ... Neheim ... Toronto. Having come across in Niederbergheim some Havermann-variant names, specifically Haverman and Habermann, suggests to me that Niederbergheim may have been the local origin point of the Havermann clan, say circa 1700.
