there are two Aigen in nowadays Austria, Aigen im Ennstal, which is in Styria, and Aigen im Mühlkreis, which is in Upper Austria north of the Danube. There is no Eigen.
There exist no families Schmider or Schmieder or else (Schmiderer, Schmidinger) in or around these places, now.
I do not know, whether there are more places Aigen in other countries of the former empire of Österreich Ungarn.
In Austria there are now Schmider (12), Schmiderer (70), Schmieder (60) and Schmiederer (20), estimated.
