|Hitler's Family Tree (Click the image above to see a larger, more readable version).|
Adolf Hitler's family tree is complicated. 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. Alois Schicklgruber did change his name on January 7, 1877 to "Hitler," which was the only form of the last name that his son, Adolf, used.
The family tree is filled with multiple marriages.
Look carefully at the marriage dates and the birth dates of their children. Many children were born illegitimately or born only a couple months after marriage. Although the graph shows Johann Georg Hiedler as Alois Schicklgruber's father, this is a contested issue.
Did you notice that Hitler had a living sister? We often think of him as a loner, but his sister Paula survived him.
Also, Alois Schicklgruber's first wife has not been included. He married Anna Glassl-Hörer (1823-1883) 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.
