The only information we have is from Mrs Panula's biography:
"On the Titanic Ernesti and Jaakko were, as unmarried men, berthed towards the bow of the ship. Maria and her 3 younger sons shared a cabin in the stern with Anna Turja. Turja later told, that one of the older boys had come from the bow and woken them." - Looking at Anna Turja's biography it seems that Sanni Riihivuori was also in the room. - She was travelling with the Panula family.
