Another source that the son of the widow of Tzorphath was Yonah (Jonah):
Pirkey d’Rabi Eliezer 33:
Rabbi Shimon said: It is through the power of charity that the dead are destined to be resurrected. From where do we learn this? From Eliyahu (Elijah) the Tishbite who would go from mountain to mountain and from cave to cave. He went to Tzorphat and a widow received him with great honor. She was the mother of Yonah (Jonah), and from her bread and from her oil he, she and her son ate and drank… After some days, her son became sick and died… The woman said to him, ‘Did you come to me to cause my iniquity to be remembered [i.e. because I am so deficient in merit compared to you, your presence causes me to appear wicked in G-d’s eyes (based on Rashi’s comments to Kings 17:18)] so that my son should die? Rather, take what you have brought me and bring me my son!’ Eliyahu stood up and prayed before the Holy One Blessed is He and said: ‘Master of the Universe, all the evils that have passed over me and over my head are not enough, but even this woman, whom I know has spoken against me harshly out of anguish over her son. Now the generations will learn that there is resurrection of the dead! Return the life of the boy!’ [G-d] accepted his [prayer].
