I am descended from those Amana Heidels. Nope, not too many of us out here. My great grandparents were elders there in Middle Amana. My grandfather as you put it 'got away' in 1910 when he was 15 yrs old to a foundry job in Davenport. Life was good to those living in the Amanas but not real exciting I think for young men and women. My father as a boy enjoyed his summers there in the 1920s and 30s.
