(I ask for indulgence from my usual readers to allow me to write about something that is not about Filipino genealogy. This article is nevertheless about genealogy, still, albeit about the British royal family.)
Whatever the truth about that first encounter, the genealogical connection between the two was well-established. It was indeed common knowledge within the royal family and the circle they circulated with that Camilla's great-grandmother, Alice Keppel (nee Edmonstone) met then-Prince Edward (later King Edward VII) in 1898 and became his mistress. While King Edward had a playboy reputation, Alice Keppel was unique in her position as the King's mistress because most people not only tolerated their affair but even approved of it. People said that the King, who had a temper, was a much better person when he started seeing Alice Keppel as she was the only one who could calm him down. Alice's husband, the Hon. George Keppel, would discreetly be out of the house whenever the king visited Alice at her home. Best of all, Queen Alexandra, wife of King Edward, was not only tolerant of but approved of Alice Keppel. In fact, she was with the Queen in 1910 when the King was on his deathbed. Some might not really understand the arrangement, but this was from a different era and when seen from the lens of that generation we know that such things were common and accepted.
