Editing House of Savoy-Carignano (section)

==France==
In anticipation of this inheritance, Thomas Francis and Marie did not establish themselves at his brother's ducal capital, Turin, but dwelt in [[Paris]], where Marie enjoyed the exalted rank of a ''[[prince du sang|princesse du sang]]'', being a second cousin of King [[Louis XIII]]. It was arranged that Thomas Francis, as son of a reigning monarch, would hold the rank of first among the ''[[princes étrangers]]'' at the French court—taking precedence even before the formerly all-powerful [[House of Guise]], whose kinship to the sovereign [[Duke of Lorraine]] was more remote.<ref name=Spanheim107/>

Thomas Francis was appointed ''[[Grand Master of France|Grand Maître]]'' of the king's household, briefly replacing the traitorous ''[[Grand Condé]]''. He engaged the services of the distinguished grammarian and courtier [[Claude Favre de Vaugelas]] as tutor for his children. The prospect of Marie's eventual succession to the Swiss principality of [[Canton of Neuchâtel|Neuchâtel]], near Savoy, was foiled in 1643 by the king's decision to [[Legitimacy (family law)|legitimate]] Louis Henri de Bourbon, ''[[Knight|chevalier]]'' de Soissons (1640–1703), a son of Marie's late brother. Although this prevented the substitution of Savoyard for French influence in that region, it left Thomas with little more than the empty title of prince de Carignan. Marie eventually inherited her brother's main holding in France, the county of Soissons; this would be established as a [[appanage|secundogeniture]] for the French branch of the family. After Thomas Francis, the senior branch of his descendants [[repatriated]] to Savoy, alternately marrying French, Italian, and German princesses.<ref name=Miroslav/>
