If it was village Dittersbach in the Vicariate Lanškroun, today in Czech village Horní Dobrouč in district Ústí nad Orlicí, then registers are available online on the website: http://vychodoceskearchivy.cz/zamrsk/matriky/
. You need to download the whole registers from the site. Parish was in a nearby village Dolní Čermná, from 1898 it was a separate parish.
There are with the same name in Eastern Bohemia also village Dittersbach = today Stašov, in district Svitavy or today Jetřichov, in district Náchod… But in Horní Dobrouč in district Ústí nad Orlicí, as far I know (from old cadastral maps), the family Benesch lived in the 19th century.
