Although referred to at the wedding on 24 November 1787 by the title "Baroness Geyer von Geyersberg" by her fiance, her marriage to the Margrave Charles Frederick, who had been widowed since 1783, was at the time deemed morganatic because she was regarded as of unequal rank to the prince.

[2] In July 1799 letters patent were issued by the Holy Roman Emperor Francis II, of retroactive effect to 12 May 1796, elevating her to the Imperial title Countess of Hochberg.

[1] Although Louise Caroline's children were not initially legally recognised as of dynastic rank, on 20 February 1796 their father clarified in writing (subsequently co-signed by his elder sons) that the couple's sons were eligible to succeed to the margravial throne in order of male primogeniture after extinction of the male issue of his first marriage, who were by then the only remaining dynasts of the House of Baden.

[1] On 10 September 1806, after the abolition of the Holy Roman Empire and assumption of the fully sovereign title Grand Duke of Baden, Charles Frederick confirmed the dynastic status of the sons of his second marriage.

On 4 October 1817, as neither he nor the other sons from his grandfather's first marriage had surviving male descendants, Charles confirmed the succession rights of his half-uncles, granting each the title, Prince and Margrave of Baden, and the style of Highness.

He asked the princely congress in Aachen on 20 November 1818, just weeks before his death, to confirm the succession rights of the sons of Louise Caroline.

When Kaspar Hauser was found, rumour had it that he was this first-born prince of Baden, allegedly spirited away at birth and raised without knowledge of his royal ancestry.
