  Hitler's father, Alois Hitler (1837–1903), was the illegitimate child of Maria Schicklgruber. The baptismal register did not show the name of his father, and Alois initially bore his mother's surname, "Schicklgruber". In 1842, Johann Georg Hiedler married Alois's mother. Alois was brought up in the family of Hiedler's brother, Johann Nepomuk Hiedler. In 1876, Alois was made legitimate and his baptismal record annotated by a priest to register Johann Georg Hiedler as Alois's father (recorded as "Georg Hitler"). Alois then assumed the surname "Hitler", also spelled "Hiedler", "Hüttler", or "Huettler". The name is probably based on the German word Hütte (lit. ' hut '), and has the meaning "one who lives in a hut".
  
  Nazi official Hans Frank suggested that Alois's mother had been employed as a housekeeper by a Jewish family in Graz, and that the family's 19-year-old son Leopold Frankenberger had fathered Alois, a claim that came to be known as the Frankenberger thesis. No Frankenberger was registered in Graz during that period, no record has been produced of Leopold Frankenberger's existence, so historians dismiss the claim that Alois's father was Jewish.
