Hi Nick,
In her affidavit Emily Ryerson says: we were in the large cabins on B deck, very far aft. That would seem to rule out rooms as far forward as B-57 to B-63.
Where did you get those room numbers from?
Mrs Ryerson also says: "I went back then and told Miss Bowen and my daughter, who were in the next room, to dress immediately, roused my husband and the two younger children, who were in a room on the other side, and then remembered my maid, who had a room near us."
Firstly what does "on the other side" mean? The other side of Mr and Mrs Ryerson; or of Miss Bowen and the oldest Ryerson daughter?
By saying that her maid had a room near us suggests that it was not entered from the same athwartship's passageway as the room Mrs Ryerson herself occupied; but if the rooms were not B-57; B-59 and B-63 then you are not limited to placing Mr and Mrs in either the forward or after of the three rooms which takes us back to "a room on the other side". Of whom?
Mrs Ryerson also says: "and saw far off people hurrying on deck." I believe that can only be understood as people in the First Class Entrance. Again rooms B-57; B-59 and B-63 are too far forward. Rooms closer to the After Expansion Joint are more likely. Tentatively I would suggest B-77; B-81 and B-83 with B-79 or B-85 for the maid.
