Hi,
I believe that Ignatz Ollinger was the son of Jakab and his first wife, Anna Falkauer. Anna Schlecter was the second wife (they married in 1845, at the ages of 44 and 48, respectively). I only know this because I have copies of the Andrásfalva Catholic Marriage records (which were not microfilmed by the LDS).
I also show two siblings of Ignatz: Anna, who married János Daradics, and Adam, who married Rosalia Appel.
