Anna Scharoch

"Guido von Seyffertitz, born in Innsbruck, was a well respected politician whose family lineage impressed his wife-to-be Anna Butler Clonblough, a native of Haimhausen, but whose own family descended from a good name in Ireland. Gustav's father died when he was only three years old, and his mother remarried in Vienna after her husband's death."
