Royal Profile: Prince Antoine de Ligne-La Trémoïlle

Prince Antoine Tau Edouard Adrien de Ligne-La Trémoïlle was born 10 January 2019 as the son of Isabella Orsini, Princess de Ligne de La Trémoïlle and Prince Édouard Lamoral Rodolphe de Ligne de La Trémoïlle {Source}. 

The young prince has two elder sisters:

1. Princess Althea Isabelle Sophie de Ligne de la Trémoïlle (2010)
2. Princess Athénaïs Allegra Isabella de Ligne de la Trémoïlle (2014)

As Belgium is a monarchy which confers and recognizes hereditary titles of nobility, the right of the Ligne la Trémoïlle children to the prefix of prince/ss and to the style of Highness is legal—not a courtesy title; all members of the House of Ligne have been entitled to princely rank and to the Altesse in Belgium since 31 May 1923 {Source: Genealogishes Handbuch des Adels: Furstliche Hauser Band XIV.
