DM – The truth of the matter is -there is no such thing as Oberlanders. The people in that area were either Hunks or Yekkes.
If people started taking others’ Minhagim because they lived in the same area -doesn’t make this right. It’s just like if a Yekke lives in BP and Davens in a Chassidishe place and starts doing all the Minhagim that they do.
