Record Office: emigration to Canada

[julip]

Would anyone look up emigration records for the following family for me?

Robert Stevenson b1800c Dumfrieshire ,Scotland
Agness Stevenson b 1801 Hutton Dumfrieshire ,Scotland
Mary Stevenson b18128 Hutton , Dumfrieshire, Scotland
Martha Stevenson b 1831, Hutton , Dumfrieshire , Scotland
Jean Stevenson b 1833 , Applegarth Dumfries, Scotland

I can`t find them on Dumfries 1841 or 1851 census, or Scotlands People, so it is possible they emigrated to Canada.

Any help would be very much appreciated, EP.
