Hello Louise, the National Archives at Kew has the officers service records of the Merchant Navy from 1845-1965, as far as I'm aware they're not available online so you'd have to go there to read them, or get someone to do it for you. If you Google 'merchant navy', you'll get a list of the forums that are related to that service, and I'm sure there'll be lots of people willing to help you on them......Good Luck................Alex PS all the docs. at Kew, on the merchant service are under the heading BT/ I think they were under the old Board of Trade......
