They say it in the show that he is from the Eastland disaster. A ship that went down while in port in the Chicago river three years after the Titanic. It was mostly carring working class first and second generation immigrations to a company picnic when it lested to starboard and trapped them below deck and into the river before rolling. The cause was most likely due to poor countrol of the ship and it being a high seating industry ship that was not designed for passangers. Ask a mortician has a great video on the topic.
