I have translated the following bit of information about my ancestor, the Prince of Niscemi, from Catalan. I was wondering if someone could take a look at it and tell me what you think "the representation of the line" means?
Don't know if this is the correct section of the forum to post this question. Thank you!!!

"Jeroni de Vallgornera i de Cardona (died 1690), who in his last will bequeathed Albons and the tower of Caldes de Montbui to his Sicilian relative, the prince of Niscemi. The representation of the line, however, passed to the descendants of his aunts Paula de Vallgornera and Santjust"

here is the original text

Jeroni de Vallgornera i de Cardona (mort el 1690), el qual en el seu darrer testament deixà Albons i la torre de Caldes de Montbui al seu parent sicilià el príncep de Niscemi. La representació de la línia, però, passà als descendents de la seva tia Paula de Vallgornera i de Santjust

I think it means that, though he left some goods to the prince of Nisceni, his nobiliar titles were passed to the descendants of his aunt.

that makes total sense. Thank you for your thoughts!
