Alois Hitler was born on 13 January 1882 in Vienna, Lower Austria, Austria-Hungary. He was married to Hedwig Heidemann and Bridget Dowling. He died on 20 May 1956 in Hamburg, West Germany.
As his father was married to another woman when Alois was born, his mother gave Alois her surname, Matzelsberger. Alois's parents married on May 22, 1883, 46 days after Alois's father's wife died.
