My August Wilhelm Stanke was b. 5 Feb 1856 in Gerzlow, Brandenburg, Prussia.He married Agnes Ludevika Elizabeth Halle on 5 Jun 1876.(She was born 28 Jun 1855 in the same town.)They arrived at Ellis Island, NY on 2 May 1903 -- several of their thirteen children immigrating with them.
August and his wife both died in Idaho.He, in 1923; she, in 1934.(I can give you the exact dates and the cemetery, if you need them.I don't have them here at my office.)I know they're both in a cemetery in Boise.
Still not sure if this August fits with your family -- you would know better than I.Let me know if I can provide additional info.Most of what I have runs "south" from August.
