The Duke's exit from the final remnants of royal life has not only reshaped his future - it's creating waves through his immediate relatives too.
His ex-wife has now lost her duchess title and will simply be known as Sarah Ferguson.
For Sarah, 66, the transition will be the most visible.
Throughout this period, she has maintained the honorary royal post-marital designation Sarah, Duchess of York. Now, she returns to her maiden name of Ferguson.
"She has lost a certain prestige over this," said one royal commentator. "She certainly does use the title – including her Twitter bio is @SarahTheDuchess."
But the loss of her title may affect her much less than the controversy she's dealing with independently about her own links with Jeffrey Epstein.
Recently, multiple organizations removed her as ambassador after an email from 2011 showed that she referred to Epstein her "greatest ally" and seemed to apologise for her public criticism of him.
Away from her philanthropy, Ferguson also has various business ventures.
And these ventures, are more probable to be impacted by the Epstein controversy than any change in title, notes one royal commentator.
But Ferguson has been a great survivor in royal circles. She has continued recovering strongly.
"She is the supreme perseverer and master of reinvention," said one monarchy writer.
For the couple's offspring, Beatrice, 37, and Eugenie, 35, there's no official alteration.
They continue to be referred to as royal princesses, which they have been granted since their birth.
Additionally there is no change to the line of succession.
The prince stays eighth in line to the crown, followed by his daughters Beatrice and Eugenie, in ninth and twelfth place in that order.
But in practice their positions are "distant" and will likely become even more remote as time goes on.
Beatrice and Eugenie are also presently non-working royals, and while they occasionally take on roles – The younger princess was recently announced as a advisor for the monarch's charity network – experts also say they "can't see a world" in which they would step up into official responsibilities.
"Regarding Beatrice and Eugenie are concerned, I think there's an appreciation of the reality that this scandal doesn't involve them, and it's not fair for it to impact them personally in the separate paths they are building for themselves," says one monarchy analyst.
"Their daughters are most unfortunate affected parties, they've had to endure quietly and have been dignified in their reserve," states another monarchy writer.
Ultimately, there seems to be little doubt that the person who will be most impacted by all of this will be the Duke himself.
For someone who always liked the royal privileges, the pomp and the ceremony, the relinquishment of his honors is profoundly embarrassing.
Therefore lacking these, on a individual basis, will significantly count.
