Hello relative, I suppose that you mean Jean Alex Julius Adler: *19 nov 1844, Göteborg domkyrkoförsamlingen, Sweden. According to second hand info: †1925 Chicago.
If that is the person you search, I think we can have an amusing cooperation.
Since I am researching descendants of Christopher Jubel (1741-1826) (my mmmffff, Jan's fmf) I have some data about him, but unfortunately not more about his life in USA. I can give you the name of the researcher from where I got the "1925 Chicago" info if you mail me. And of course I am am very interested if someone else knows anything about this branch of the Adler tree!
