Hello Chris,
You've done a fantastic job. My husband is a descendant of Oscar Pedersen who did the narrative in the Gloucester Citizen on Thursday 29th July 1915 and we just found out that he was on the ship the Sapho when it left Gloucester for Hamburg on July 31, 1914. "On August 5, while taking in a general cargo at Hamburg, the crew first heard that war had broken out between Great Britain and Germany. The chief of the dock police boarded the vessel and informed the master that his ship was under detention. Five days later on August 10 a police guard was put on board the ship and the officers and crew were detained as prisoners aboard the vessel until August 15 when they were removed to a prison hulk in the harbour and the Sapho was taken possession of by the harbour authorities They remained on board the hulk close prisoners until November 6 when they were taken ashore, put on a train and carried to Ruhleben, where Mr Pedersen remained a prisoner until July 6 on the present year, when, on account of his age (he is 67) and ill-health, he was released under the scheme of exchange of prisoners"
I would enjoy hearing from you or other descendants of Oscar Pedersen of Gloucester.
