Stockton Rush, one of those who died on the Titan submersible in the North Atlantic, was married to a descendant of two first-class passengers who died when the Titanic sank in 1912 after hitting an iceberg, the New York Times has said.
Mr Rush, who is married to Wendy Rush, was chief executive of US-based OceanGate Expeditions.
The company operates the Titan submersible that went missing on Sunday as it descended with him and four others to visit the Titanic wreck off Canada's coast.

Wendy Rush is a great-great-granddaughter of the retailing magnate Isidor Straus and his wife Ida.
They were two of the wealthiest people on the Titanic's maiden voyage when it sank after hitting an iceberg.
The tragic tale of Isidor Straus, co-owner of Macy's department store and his wife Ida, is recounted in James Cameron's blockbuster film "Titanic".
Ms Rush is a communications director with Oceangate and has previously undertaken three expeditions to the wreckage in 2021, 2022 and 2023, according to her LinkedIn page.
