My grandmother was Berta W. Pittner, Her mum was Berta J. Adler, born 1872 in Vienna. Berta J. Adler was the daughter of Johann Adler, born 1830 in Vienna and Wilhelmina Weigl, born 1842. Do you have information for me? Can you take me further back? And/Or would you like to know more about these people and their descendants? Please let me know. Happy hunting, Maresli.
