Agreed, Phil. It looks like a one-off feature from a journalist who has no special interest in Titanic and sourced most of his information here at ET. It certainly does cast a wide net in trawling those whose 'names were obviously of Arab heritage'!
Have you come across a book on the Lebanese passengers by Leila Elias? It was said to be 'with a publisher' a couple of years ago but I've heard nothing since.
