The Allison's cabin allocations on the Cave List
Cabin C-26 was located on the port side on C Deck. It was occupied by Hudson Joshua Creighton Allison and his wife Bess Waldo.
The Cave List stated that the Allison family stayed in this cabin and C-22, not using the nearby vacant cabin C-24. If that's true, then Mr and Mrs Allison with Loraine would have probably have occupied C-26 with the others in C-22.
But if the Allisons used cabin C-24 after all, Loraine would most likely be reassigned to C-24 along with maid Sarah Daniels. After the disaster when Miss Alice Cooper and Miss Daniels stayed with the family, it became known that this may have happened.
