Answer:
Adolf Schickelgruber changed his name to Adolf Hitler, a not uncommon sirname in the Corinthian province of Austria where he was born, and where indeed some of his relatives had that name. Europe's other modern mass murderer, Josef Stalin, went one step further and created his own surname, Stalin, the man of steel.
Explanation:
It is alleged that Hitler had a son, Jean-Marie Loret, with a Frenchwoman named Charlotte Lobjoie. Jean-Marie Loret was born in March 1918 and died in 1985, aged 67.
