I came across a title with a "from A over B to C" structure, namely
"Facts and events from the USA over the UK to Australia"
Now, I personally think this is incorrect (potentially a carbon copy of a German expression, if a Google search is to be trusted - but I'm no German expert myself), and would personally use either "from A to B to C" or "from A through B to C".
Am I wrong in thinking that "from A over B to C" is not proper English? Perhaps it's just an expression I've never come across?
EDIT: Also, the contest this title refers to supposedly also covers stuff about Ireland, Canada and New Zealand, so I would assume the three countries provided in the title are not supposed to be an exhaustive list. Not sure if that helps, really.
