James Hewitt? Yes, he's denied being Harry's father and apparently the affair started a few years after Harry was already born. They really do/did look alike tho, but if you look at pics of a young Philip, I think you can see a resemblance to Harry.Oh my, I have probably confused Castle Goring with Newstead Abbey.
I developed a new interest in the royals during the funeral proceedings. Last thing I remember from decades ago were the rumours concerning Harry, whether he was actually the son of Diana's riding instrutor. Has this mystery been solved in the meantime?
