Wendy Rush – who is the wife of Stockton Rush, the CEO of OceanGate Expeditions and the pilot of the submarine that has been missing since Sunday (June 18) – is the descendent of a couple who died on the original Titanic in 1912.

On Wednesday, the New York Times confirmed that Wendy is related to Isidor Straus and Ida, who were depicted in James Cameron‘s 1997 film based on the tragedy.

The outlet writes: “Ms. Rush’s ancestors on the Titanic are perhaps best known for their tragic love story. Survivors of the disaster recalled seeing Isidor Straus refuse a seat on a lifeboat when women and children were still waiting to flee the sinking liner. Ida Straus, his wife of four decades, declared that she would not leave her husband, and the two were seen standing arm in arm on the Titanic’s deck as the ship went down.”

Isidor was the co-owner of Macy’s and one of the wealthiest people aboard the Titanic. Wendy is Isidor and Ida‘s great-great-granddaughter.

Rescue missions for the missing submersible are currently ongoing, with specialists speculating that the vessel has less than 24 hours worth of oxygen left. Earlier today, a passenger who rode on the missing Titanic research submersible revealed what the experience is actually like.
