Hitler's Family Tree Adolf Hitler's Family Tree. Jennifer Rosenberg Adolf Hitler's family tree is a complicated one. You will notice that the last name "Hitler" had many variations that were often used almost interchangeably. Some of the common variances were Hitler, Hiedler, Hüttler, Hytler, and Hittler. Adolf's father Alois Schicklgruber did change his name on January 7, 1877, to "Hitler"—the only form of the last name that his son used. His immediate family tree is filled with multiple marriages. In the above image, look carefully at the marriage dates and the birth dates of Hitler's many relatives. Several of these children were born illegitimately or only a couple months after marriage. This gave rise to many disputes such as the contested issue of whether or not Johann Georg Hiedler was Alois Schicklgruber's father (as depicted in the chart above).

Adolf's Parents Adolf Hitler's father Alois Schicklgruber had two wives before Adolf's mother. The first, Anna Glassl-Hörer (1823–1883) he married in October 1873. Anna became an invalid soon after the marriage, in 1880 she filed for a separation, and she died three years later. Alois and Anna had no children together. Alois' second wife, Franziska "Fanni" Matzelsberger (Hitler) married Alois at 19 years of age and gave birth to two children, Alois Jr​., and Angela Hitler. Fanni died of tuberculosis at the age of 24. Not long after Fanni's death, Alois married Klara Pölzl, his housekeeper and Adolf's mother, whom he had hired during his first marriage. Klara and Alois had six children together, half of which died before the age of 2. Only Adolf and his youngest sister Paula survived into adulthood. Klara died of breast cancer in 1908 when Adolf was 19 years old.

Adolf Hitler's Siblings Although Hitler's immediate family tree lists five full-blood siblings, all of his older siblings died in infancy. Gustav Hitler, born May 17, 1885, died nearly seven months later of diphtheria. The next born, Ida on September 25, 1886, died less than two years later of the same disease. Otto Hitler was born and died in the autumn of 1887. Another of Adolf's siblings, Edmund, was born after Adolf in March 1894 but died of measles at the age of six. Adolf's youngest sister and only sibling to survive into adulthood was born in 1896 and died of a stroke in 1960. Adolf committed suicide in 1945, and Paula, born in 1896, lived until she died of natural causes in 1960. From his father's previous marriage, Adolf had two half-siblings, Alois Jr. and Angela Hitler. Both married and had children, some of whom are still alive today. Angela married Leo Raubal and had three children, Adolf's nephew Leo Rudolf (died in 1977) and nieces Angela "Geli" (died in 1931), and Elfriede (died in 1993).
