Queen Wilhelmina of The Netherlands, born 31 August 1880

I think one of the biggest age differences is the one of
Countess Bigitta Bernadotte af Wisborg (born 1933)
and Countess Diana Bernadotte af Wisborg (born 1982)

age difference 48 years and 11 months

Shouldn't there be two categories here?

1. Largest age difference, both parents in common
2. Largest age difference, one parent in common (most often, but not always, the father)

King Konstantinos I of Greece and Prince Christoforos 20 years.
