have you visited the Kestell-Kautzer Familiy Tree?http://www.bytehead.com/~kautzer/kautza_ig.html#thomas
Anna might have been born as a Kautza and married as a Kautzer. You wrote me, the marriage record at St. Gregory's lists Kautzer. What about her birth record? Town Eaton?
The Kestell-Kautzer website gives Louisa Bechmann as her mother.
