From NSWiki
Bertrand, Marquis de Pottin (born 1980) is the son of Aliénor, Duchess de Pottin, and Baron Constantin de Lanoye.
His siblings bear the surname "Lanoye-Pottin", but Bertrand, as heir of the ducal title, uses the subsidiary title of Marquis de Pottin, without the name Lanoye.
In 2011 he married Countess Sophie von Meissenfeld. They have two children: Marie Anne (born 2012) and Eric (born 2013).
Bertrand works for a bank in Markund. He is also a Chamberlain to King George IV.
