I do believe we have a connection here. Below is info on my grandmother's (Olga Adeleide Schubert) sister:
Liddy Schubert Liddy married Wilhelm Troger . They had the following children: 11 Fi.Hanni Troger . 12 F ii.Lena Troger
My mother, aunt and uncle were all born in Wildenfels.The family has come to a halt researching theSchubert family and I'm praying that you might be related and have some valuable information on the Schubert and/or Backer family that lived there. The Backers (Fritz and Olga moved to England in 1919 when my mother was 1 year old.
Please let me know if we have something going here.
