The author and/or title of a book that I read as a child (so must have been in the 1980s, but could have been a more classic book)
All I can remember is that it was about a family on a ship (liner) that was going to America and there were two families (I think), one wealthier than the other but willing to share!
This must be the longest of long shots! Anyone got any ideas!!?
Thanks
