Admin note: I haven't personally done any of my own research on Captain Owen Owen. Don Charlwood writes in his book The Wreck of the Netherby:
Owens was born in Wales in 1821 and was on his first voyage on the Netherby. He returned to England on the Black Ball ship Flying Cloud and lost his job with the Black Ball Line on 7 November 1866. He was the captain of the Samuel 1867-74 and the Pegasus from 1874-83. He died on 24 January 1893 and is buried in Morfa Nefyn, Wales.
