- ―Orville J. Simpson in the Simpsons Tapped out
Orville J. Simpson, or Great-Grandpa Simpson also known as Grandpa Orville Simpson was one of the five children of "Old Tut" and "Happy" Dinsdale, the father of Abe Simpson and the paternal grandfather of Homer Simpson.
Orville J. Simpson was born in an unidentified country (presumably Scotland), and married Yuma Hickman in the early 1900s. The couple had at least twelve children, including Hubert, Tyrone, Cyrus, Hortense, Fester, Bill, Chet and Abraham.
Assuming Abe is to be trusted with his stories, Orville, Yuma Hickman and their children emigrated to America on a steamboat from an unspecified country (presumably that of Scotland, Ireland, or Northeast England) and moved into the Statue of Liberty. After a few years of living there, they were forced to move out when they filled the head with too much garbage. Their family then moved to Springfield, which was located in an unidentified state. While in America, the couple had two children, Bill and Chet.
Orville was seen in Heaven by Bart after getting hit by a car, strangling young Homer, hinting the habit is a family trait. However, this is more likely to be a concussion-related dream that Bart had while he was brought to the hospital. Orville is present in Grampa's story when Grampa tells the family of his arrival in the U.S.
In "Mathlete's Feat", it's mentioned that he raised Abraham and his eleven dead siblings on crick water.
In "The Winter of His Content", Homer reveals that Orville is alive, yet Grampa never visits him or acknowledges his existence; defending his own behavior towards Grampa. Lisa is shocked about Orville being alive and nervously changes the subject.
Orville appeared again in "Dad Behavior" in which, during a (highly inaccurate) flashback, he hurls a baby Abe at the sun in response to him throwing up milk on his shirt. During this flashback, both Orville's physique and vocabulary are similar to that of Popeye. His voice is also similar to that of Krusty the Clown.
In another flashback, Orville, as a "professional child-beater", is shown to have owned a disciplinary school, where he taught fathers how to punish disagreeable children, by strangling Abe as a demonstration. Despite this, his father remained unimpressed, and strangled him.
