The original post is so old perhaps the enquirer has disappeared - however I am wondering if the mistake could be because of verbal, rather than documentary evidence? Hohenems is/was Austria (Austro-Hungarian Empire) but it is also almost on the Swiss border in the most westerly Austrian Province, Vorarlberg, and there is a Peiden Bad in Switzerland, not a thousand miles away. People did move around so perhaps he was born in Switzerland but lived most of his life, and died, in Austria(Austro-Hungary) - maybe Mother was Swiss? Another point is that Peiden would sound like Pieden (apple pie!) to English speaking ears which could have motivated someone to write down Pieden instead of Peiden. In the absence of other suggestions, it might be worth considering.
