Hello,
I am a Winkler born in Sopron. My mother was Winkler born in Sopron. Her father was Jozsef Winkler born in Komárom to Jakab Winkler and Mary Oberlander. Mary Oberlander moved to Györ when her husband died. She was old and my thinking is that she moved to be close to other Winkler family members.
