Hi,Anna Pollack was the daughter of Mathias and Anna Wachtler Pollack.Mathias (Matthew) was born in 1846 in Austria, possibly in Mason, Szentjanos, Austria where his wife, Anna was born in 1848. Anna's sister Julia Anna who married Philip Peter Miller, was my grandmother.
I have some information on the Pollack family, but not much on the Laux.A Laux family lived next to my grandparents, and I remember calling her "Aunt Laux" so might have been your Anna.

I have my ancestry posted on World Connect - type in Pollack, Mathias - my family is Boicourtbylines.
