Josef Hermann may have had sisters and brothers born after October 1, 1895. The civil records may have more info on his parents than the church records, such as birth places and dates (at least ages).
Duplicates of the civil records until 1920 were filmed by LDS and can be ordered and viewed at LDS Family History libraries.
In southern Burgenland, the duplicate church matrikels start in 1828. They are also available on microfilm from LDS, not only at the National Archives.
