In 1876, three years after Alois Hitler's first marriage to Anna Glasl-Hörer, Klara's uncle Alois had hired her as a household servant. She was 16 years old at the time. After the death of his second wife, Franziska Matzelsberger, in 1884, Alois and Klara were married on 7 January 1885 in a wedding held early in the morning at Hitler's rooms on the top floor of the Pommer Inn in Braunau. Alois then went to work for the day at his job as a customs official. Klara still called Alois "uncle" after the marriage. Their first son, Gustav, was born four months later, on 15 May 1885. Their second child, Ida, was born on 23 September 1886. Both infants died of diphtheria during the winter of 1886-1887. A third child, Otto, was born and died in 1887.
