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.

Nice Thread!! Good idea Koningin!!!

The age difference between Stéphanie de Luxembourg née comtesse de Lannoy (1984) and her eldest brother Jehan comte de Lannoy (1966) is 18 years.

So Jehan is in fact old enough to be father to his youngest sibling? He walked Stephanie down the aisle at her wedding in lieu of their ailing father Count Philippe. Count Jehan also caused a bit of a stir on some message boards because he is a rather attractive man, especially in his Belgian Army uniform.;)
