I am a professional genealogist and I am trying to determine is a couple, who ultimately did not board RMS Titanic, did purchase a ticket to embark at Cherbourg. I have located the manifests for Southampton and Queenstown, but not Cherbourg. Do these exist? Also, you state that for Cherbourg we have every list including the White Star contract list and the Clearance List. Can you tell me where the original lists or a microfilm or digital image might be found? I would like to view these.
