Hello99 to ME “If your family was originally from Stolin then they were never Ashkenazim/German Jews, rather they were Litvaks. So you have not “returned my family to the way of Ashkenaz”, as minhag Lita has many significant differences from minhag Ashkenaz.”
Minhag Lita is a variation of Minhag Ostreich (or Minhag Polin as it is called today). If my family was from Stlolin, there is no way to know if my family was originally from Lita, Polin, Russia or Ashkenaz, because the chasidim changed the Nusach and a host of other minhagim along the way. My father observes a cholent of Minhagim from Stolin, Lita, Ashkenaz (because my mother is a Yekke). Therefore, he suggested to me to select a coordinated and consistent set of Minhagim from an established Kehilla in Klal Yisrael. After much research, I discovered that Minhag Ashkenaz is the best specimen. And so I adopted it.
