Also, the name repetition might be important. "Margosullivan" could be the author's name, so using that in the text. Maybe the mom is a character in the story. Need to make sure the text is engaging and flows well. Check for possible coherence and clarity. If "he" is correct, perhaps it's about the mom giving a new something to a son, but that's unclear. Maybe better to go with "she" for clarity. Proceeding with that assumption.
