Anton, Tony, or Tonney, as he is listed in the censuses (never as Herman), is listed in the 1930 census of Wilmerding, Allegheny County under the misindexed name of Anton H. Ohnmacht. He was 62 and a widower.
You didn't say if you were looking for info on him going back or not, but you might be interested to know he appears in the 1880 census as Tony Oberneck in Butler County, OH. He appears in the 1870 census in the same location under the name Tonney Oberricht.
You can find his birth record under Ohio Births and Christenings. He was born Dec 15, 1867 to Ferndinand Oberncht and Margaret Upseng. You can also find the 1850 marriage of Ferdinand to Susanna Margaret Obsing. They appear in a number of records sometimes as Obrect. You can even find Ferdinand and Margarita's Ohio death certificates which do have their parents' names (at least the father's anyway).
If you're just looking for info on the family in Allegheny County I suggest being more specific.
