Answer:
La hija de mi abuelo volvió y tuvo comida.
Explanation:
In my opinion, the original sentence sounds funny to begin with, but this is how you would change those infinitives into their preterite forms for the ¨él, ella, usted¨ pronouns.
Volver - volvió
Tener - tuvo
Also, ¨hija¨ is a feminine noun so it should be ¨la hija,¨not ¨el hija¨
