For me, Elegran, its the terrific interest in the doings of the second daughter of the third son of the monarch, and what she calls her son. (Actually I don't know if that's all accurate, I don't keep up
)
Or wondering why the fourth son of the monarch won't get called by a title that was re-instituted for his father but doesn't have any meaning at all.
None of it matters 
If charities and so on want to have particular people as their patrons, good luck to them. But there is definitely a correlation between the interest shown in some of these "minor" royals and your common or garden celebrity.
If Eugenie was just a nice posh girl who worked in a gallery and married a millionaire, would we be interested in what she called her son?
Unbearable grief compounded by our adult children’s reactions
