Teresa Cristina married in Salzburg; the Baron Lamoral Taxis of Bordogna and Valnigra, based in Italy, and who belonged to the princely family of Thurn and Taxis. The baron allowed his children to be registered as Brazilians,[5] so that they could remain in the line of succession of the brazilian Braganzas. This couple left as heir of their names and traditions Carlos Tasso of Saxe-Coburg and Braganza.
The members of this branch would not normally be eligible for the dignity of Dom; since titles of nobility is not transmitted through the mother by the nobility rules of Brazil given that their claim to that dignity came from Princess Leopoldina.
However, after the death of Princess Leopoldina, her first two sons; Peter Augusto and August Leopold, were taken to Brazil to be raised as heirs to the Brazilian imperial throne, given the difficulty of their aunt Imperial Princess Isabel, to conceive children. Princes Pedro Augusto August and August Leopold began to receive the treatment of Highness and Dom, being for all intents and purposes, Princes of Brazil. However, this condition weakened with the birth of Pedro de Alcântara, first male of Princess Isabel and Count of Eu, and his brothers.
