The great Sephardic Torah authority and Kabbalist, Rabbi Chaim Palachi (1788-1869) of Izmir, Turkey, records a custom that each member of the family should say the blessing over a specifically-designated fruit:

Father: should say "mezonot" over a grain product, related to his wish for success in earning a livelihood, which is represented by wheat, as in the verse, "He shall satisfy you with the fat of wheat." (Ps. 147:14)

Mother/wife: should say the blessing of "ha'etz" over grapes, as the verse in Ps. (128:3) compares the wife of a G‑d fearing man to a "fruitful vine."

Sons: should eat olives in accordance to the above verse which too likens the sons of G‑d fearing man to young olive trees.

Daughters: should eat pomegranates and walnuts which are covered by an out shell or covering, symbolic of tzeniut –modesty- that is required of all Jewish girls.

Young children: should eat apples, in honor of the courageous Israelite women during the Egyptian bondage who secretly delivered their babies in the apple orchards.
