Yuma Simpson (née Hickman), or Great Grandma Simpson is Homer's paternal grandmother from "The Old Country", which has similar characteristics to Ireland or Scotland. Grampa said "Back in the old country, I don't remember which one..." Yuma was the daughter of Willard Hickman and Theodora Hutshing married Orville Simpson in the early 1900s. For a few years, they lived inside the Statue of Liberty, along with their sons, until the head of it was filled with too much garbage. With their sons they moved to Springfield, where Yuma had another child and eventually died. Yuma passed away when Marge was pregnant with Bart and long after her husband.
