OceanGate CEO's wife has ties to Titanic tragedy.

Wendy Rush, the wife of missing OceanGate CEO Stockton Rush, is related to Isidor and Ida Straus, who died together in the sinking of the Titanic in 1912. Wendy Rush is the great-great-granddaughter of the couple, who were first-class passengers on the ship. Stockton Rush is currently missing along with three others after their submersible lost connection with its support ship during an underwater expedition to the Titanic wreckage. Search efforts are underway, and it is believed that the passengers may have less than 24 hours of oxygen left.
