I don't know if you viewed the emmigration records as www.ellisisland.org
(a free site) but it has the actual ship manifest, which includes more information than Ancestry. Unfortunately the page for her ship is not the right one, they apparently transposed two different ships that arrived on the same day. I have informed the website so they will fix it. You can view her passenger record transcript, and it says she was from Lunden Germany.
(Also, her name is mistranscribed as Herrnian, or Hermian) I only found it by searching for all Emma's who arrived in 1909 and were born 1891-1892. I searched first at another site, http://stevemorse.org/
Pick the Ellisisland gold search. You can put in as few or as many parameters as you want. Once you find the right person and click on the link, it takes you to the Ellis Island site - it is free, but you have to register. http://www.ellisisland.org/search/passRecord.asp?MID=2025382...
