Suntay III (Emilio III) and respondent Isabel Cojuangco-Suntay.
During his lifetime, Emilio I was married to Isabel Cojuangco, and they begot three children, namely: herein respondent, Isabel; Margarita; and Emilio II, all surnamed Cojuangco-Suntay. Emilio I’s marriage to Isabel Cojuangco was subsequently annulled. Thereafter, Emilio I had two children out of wedlock, Emilio III and Nenita Suntay Tañedo (Nenita), by two different women, Concepcion Mendoza and Isabel Santos, respectively.
Despite the illegitimate status of Emilio III, he was reared ever since he was a mere baby, nine months old, by the spouses Federico and Cristina and was an acknowledged natural child of Emilio I. Nenita is an acknowledged natural child of
