 The infertility of Princess Isabel, heir presumptive to the crown—who would give birth to a son only after more than ten years of marriage and almost four years after her sister's death—included Leopoldina's two eldest sons on the 2nd and 3rd positions in the line of succession to the Brazilian throne.After the death of their mother, the young princes were taken by their grandfather to be raised and educated in Brazil.This situation made the princess, although involuntarily, the founder of the cadet branch of Saxe-Coburg and Braganza.
