Duke Wilhelm von Urach, along with the other adult descendants of Princess Florestine, discussed renouncing their dynastic rights in 1924 in favour of a French cousin, Léonor Guigues de Moreton, "comte" de Chabrillan, who was descended from Prince Joseph of Monaco. The count was a more remote, female-line descendant of the Grimaldi dynasty, and was next in line to the Monégasque throne after the Urachs according to the pre-1920 order of succession. However, this renunciation was never formalised. Thus, the duke considered withdrawing as a claimant to Monaco's throne (he had also been considered for the thrones of Lithuania and Alsace-Lorraine, although these monarchical opportunities never materialized), he did not choose to recognize Monaco's "selected" heir – perhaps unsurprisingly, since the 1918 law and treaty directly intruded upon his hereditary rights, excluding him from a throne for no personal act of dereliction on his part, and without compensation ("cf." Prince Ingolf of Denmark).
