I just read your post that is a couple of years old. I am looking at my mother's family tree (Zauner) and there is a Borell connection.
My mom, Anna Zauner (phonetically nicknamed Nonchee) was born in Engelsbrunn on June 5, 1923 to Teresia Schankula Zauner and Nicholas Zauner. Teresia was born in March of 1901; Nicholas was born in 1899, both born in Engelsbrunn. Nicholas’s family later moved to Dreispitz. My mother's Aunt Katherine Zauner married John Borell (Borell-Hans) and they had a daughter, Anna, who was very pretty, deaf, and communicated in whispers. She was my mother's godmother, and named her. (Nicholas?)Loefler, a widower with one son who owned a mill in Dreispitz married Anna Borell when she was in her 30s. My mom would occasionally go stay with them as a child.
My mother remembers her aunt Katerina (Katibas) Zauner Borell as being bossy:) She and her husband John Borell had two children, Anna (the deaf woman) and Peter. Peter in turn had two children, a girl named Borell-Nani (Anna), and a son Michi (probably Michael.) Nani was older than my mom, and Michi younger. Their mom was named Anna (nicknamed Miete, wife of Peter Borell.) Mom doesn't remember Miete's maiden name.
One last piece of info - Katerina Zauner Borell's parents were named Nicholas Zauner and Margaret (my mom doesn't remember her maiden name at the moment.)
Mom says everyone in the village had a nickname, probably because family names were used repeatedly, which makes things rather confusing for the descendants:)
