Nancy the Postal Lady is Spooner Street's mail carrier. She first appeared in "Death Has a Shadow", delivering welfare checks to Peter Griffin, and gave one to his wife Lois, with both not knowing that Peter was committing welfare fraud.
She was later one of Peter's Mormon wives in "The Father, the Son, and the Holy Fonz". His 'marriages' end when he is reminded by his Mormon wives that he couldn't be a Mormon and drink alcoholic beverages as he is later seen dragging multiple bags to the trash.
Nancy is voiced by Lori Alan.
She is seen in a hallucination of Peter's on a cruise ship full of deceased characters in the Panama Canal in "Coma Guy".
