Florestine was a member of the House of Grimaldi and a Princess of Monaco by birth and a member of the House of Württemberg and Duchess consort of Urach and Countess of Württemberg through her marriage to Wilhelm, 1st Duke of Urach.

[1] Florestine, according to the rules governing succession to the throne of Monaco, was able to marry without relinquishing her rights.

When her grandnephew Louis II, Prince of Monaco, ascended to the Monegasque throne, Florestine's son Wilhelm claimed his rights for his succession to the princely throne of Monaco and the Grimaldi noble titles.

However, France had undergone two wars against Germany and did not wish to see German princes ruling the Principality of Monaco.

Therefore, France reached an agreement with the principality allowing the illegitimate daughter of Louis II, Charlotte, to be his heir presumptive to the princely throne and Grimaldi noble titles.
