Thank you for posting your question on History Hub!
The record that you are requesting will not be in possession of the National Archives and Records Administration. For European ship and passenger lists, you will have a much better chance of finding this record on one of the main genealogy websites, such as Ancestry and/or FamilySearch. Please keep in mind that Ancestry is a subscription-based database, but it is available for free public use at all National Archives facilities and many public libraries. FamilySearch is free but you have to create an account with them.
You may also wish to contact the National Archives of Romania (their website can be translated into English) and/or the Turkey Directorate of State Archives (their website can be translated into English as well) for more information.
We hope this information is helpful and best of luck with your research!
