Aureliano Babilonia

Though in the book, the name is only "Aureliano", this wiki addresses it as "Aureliano Babilonia" for the sake of simplicity.

Aureliano Jose is the son of Renata Remedios Meme and her lover Mauricio Babilonia. Her grandmother Fernanda was very reluctant to accept him as a family member, unlike Ursula, who accepted bastards of Colonel Aureliano Buendia and Jose Arcadio.
