Amelie Auguste & Pedro of Brazil had 1 daughter..

.. of their own legitimately, although Amelie adopted his daughter Maria as her own, & raised and educated her personally.  They had a happy marriage.

They had only the one child, Maria Amelia, before King Pedro died of tuberculosis after fighting his brother for title and rights.   Maria Amelia became a great musician, but unfortunately also died of TB at the age of 22 without having married or had children.
