From what I've found, all of these Elijah Lee's are related. My Elijah was the son of John Riley and Arsenith Seals. The Elijah killed in the train crash was the son of William who was a brother of John Riley. The Elijah whose wife filed for a pension in Louisiana was the son of Steven and Rebecca Lee. Steven was the son of Elijah Lee, who was said to be the brother of John Riley even though I can't find proof.
