[princess olga]

I've always been fascinated by the question/topic what ('secondary') royals--i.e. siblings of Crown Princes/Princesses-- do for a living. In other words, members of royal families who do something unrelated to anything having to do with being royalty.

For example, I know that Prince Constantijn, the youngest brother of Crown Prince Willem Alexander of the Netherlands, is a consultant/advisor for a high-caliber political thinktank in Brussels. Middle brother Friso, meanwhile, earns an honest pay check working for TNO, a Dutch research institution.

Wives Mabel and Laurentien also have jobs, as director of billionaire George Soros's charity institute/lobby group, and communication advisor, respectively.

Other royal families have working members, too.
*Pavlos of Greece for example is in finance, (but what do his siblings do for a living?)
*Viscount Linley, princess Margaret's son, is a furniture maker.
*Sophie of Wessex used to own her own PR company.
*PEter Phillips works in marketing for a Formule 1 racing team I believe.
*Dutch princess Marilene works for AHOLD in marketing I think.

Can anyone fill me in about other royals with jobs? What, for example, do Spain' s infanta's do for work? How about Belgium's prince Laurent? Others? Would love to hear!
