Her other sons were also circumcised at birth. As Charles was in direct line to the throne, an announcement, in royal tradition, was posted on the gates of Buckingham Palace to that effect. Prince Charles was circumcised by a Dr Snow, a Jewish mohel, at the request of the present Queen and his father, the Duke of Edinburgh.
Circumcision in the British royal family only started with (possibly) the sons of George V - the two eldest of whom, David and Bertie, would both reign as Edward VIII and George VI - after routine infant circumcision had been promoted in late Victorian times as a prophylactic measure, with most of the British upper classes briefly adopting it. There is no evidence that George III was circumcised. This falsehood is repeatedly used as spurious evidence that the British royal family adopted circumcision. There is no evidence at all that any of Victoria's male children were circumcised as there is absolutely no corroborated historical evidence that she subscribed to the somewhat bizarre theories of the British Israelites, a sect which, without any systematic evidence, maintained that the British royal house was ultimately descended from one or several of the lost tribes of Israel.
Although persistent, there has been no evidence uncovered as to the veracity of these rumours. It did not help matters that Albert turned out to be a very highly accomplished and talented musician in his own right.
These rumours started as a result of Albert's very distinct difference in facial features from both his father and brother and because his father had Albert's mother "put away" for repeated adultery. There have, however, been persistent rumours that Albert was possibly the illegitimate son of the court's musician who was thought to be Jewish. The House of Saxe-Coburg and Gotha was Lutheran Protestant, not Catholic. That is the only link between the royal house of Saxe-Coburg and Gotha - later Windsor - and the Prussian House of Hohenzollern. Victoria and Albert's eldest daughter, also called Victoria, married Prince Frederick William of Prussia and who reigned as German Emperor only briefly owing to his premature death from cancer. "Saxe" is the French form of Saxony, which was used as the Almanach de Gotha was written in French and not German. She married Prince Albert of the House of Saxe-Coburg and Gotha. When the Duke of Kent, the last living son of George III died, his daughter, Alexandrina Victoria, acceded to the British throne, effectively the last monarch of the House of Hanover. When the last monarch of the House of Stuart, Queen Anne, died without issue, the throne passed over 52 other claimants as a result of the requirement to be Protestant, to George I of the House of Hanover.
When Elizabeth I, the last monarch of the House of Tudor, died without issue, the throne passed to the House of Stuart and James VI of Scotland and I of England. All heirs to the Spanish throne were traditionally circumcised as a result of circumcision's ancient association with royalty. To this day, the Coptic Apostolic and Autocephalous Churches of the East and the See of Rome remain mutually unrecognized and the former regard Roman Catholicism as heterodox. Wherever are you getting your history? Pope Eugene IV issued a Bull in respect of circumcision but this was in respect of the putative mutual recognition of the Holy Orders of the See of Rome and the Christian Coptic Churches which had retained the rite.
