emigrants Norway to Scotland 1850-1885

Trans-Atlantic migration is very well documented, but Im looking for info on possible sailings from Norway to Aberdeen or Leith (Edinburgh). I know Hull was a regular destination but I think the Scottish docks are more plausable, given the fact my ancester married in Edinburgh in 1885. Any advise or info would be very greatly appreciated. Feel free to email me on [email hidden]. Many thanks for reading this. Bill
