Notes:

His Serene Highness The Sovereign Prince of Monaco, ruled the Principality of Monaco for more than 50 years, making him one of the longest ruling monarchs of the 20th century. Though he was best known outside of Europe for having married American actress Grace Kelly, he was also responsible for reforms to Monaco's constitution and for expanding the principality's economy beyond its traditional gambling base. Gambling accounts for approximately three percent of the nation's annual revenue today; when Rainier ascended the throne in 1949, it accounted for more than 95 percent.

Prince Rainier had nine grandchildren:
Andrea, Charlotte and Pierre Casiraghi - children of Princess Caroline and Stefano Casiraghi;
Princess Alexandra of Hanover - daughter of Princess Caroline and Ernst August V, Prince of Hanover
Louis and Pauline Ducruet - children of Princess St?phanie and Daniel Ducruet
Jazmin Grace Grimaldi - the illegitimate daughter of Prince Albert II of Monaco and Tamara Rotolo
Alexandre Coste - the illegitimate son of Prince Albert II of Monaco and Nicole Coste
Camille Gottlieb - the illegitimate daughter of Princess St?phanie.

Rainier married Grace Kelly in Apr 1956. Grace (daughter of John Brendan "Jack" Kelly and Margaret Katherine Majer) was born on 12 Nov 1929; died on 14 Sep 1982. [Group Sheet] [Family Chart]
