The conventional idea suggested by conspiracy theorists is that Adolf Hitler was related to the Rothschild family via his paternal grandmother (Schicklegruber) who conceived his father, Alois, out of wedlock. While the Victoria's Secret thesis presents an intriguing alternative, what concerns me is whether Queen Victoria (1819-1901) was able to conceive Klara, Hitler's mother, in 1868 at the age of 49. Not saying that the queen couldn't have had another child at that advanced age, just that this account hinges on that being the case.

Führer Adolf Hanover/Hitler (1889–1962).
Führer from 1933 to 1945.

Because of the 1688 warming pan plot, Catholics were prohibited from ruling Britannia, so the Hanover dynasty was imported from Germany in 1714.

To Americans, the best known monarch of that dynasty was good King George III.

The real name of the infamous man known to the world as Adolf Hitler is Adolf Hanover. He was a grandson of Queen Victoria, and was born in Austria on April 20, 1889...

...On August 22 (1868), the queen left Lucerne for the much higher altitude of the Furka Pass, well above the tree line, and far higher than the queen had ever been before. Before her arrival, the Furka Inn was emptied of guests, and no Swiss were allowed to get even close to their queen.

Queen Victoria's Swiss baby was born on August 24–the anniversary of the St. Bart's Day Massacre.

The baby was born in the high altitude Furka Inn.

The baby girl was named Klara, and she was the precursor of Pamela Digby Churchill—the mother of Hillary Digby Churchill Clinton!
