Rose,
Some thoughts/comments.
1. Joseph and Jane were married in 1841 - but Statutory Registration did not begin in Scotland until 1855. So you will not get a 'marriage certificate' but merely a copy of the entry in the church register (OPR). It might have further snippets of information but be aware that it might say nothing more than is recorded in the IGI (i.e. there might be no further information at all).
2. I note that Joseph of the 1841 census is listed as born in Ireland whereas in the 1851 (in Penninghame, Wigtonshire) he is listed as born in Mochrum, Wigtonshire and in the 1861 (in Durham) as born in Scotland. Assuming that it is the same person (which seems more than likely) it might be that the 1841 is an error? Perhaps Joseph's parents were Irish so farmer James LITTERICK just assumed that Joseph too had been born there. In 1851 and 1861 however, it was probably Joseph himself who was providing the information so one might normally expect it to be more reliable (though, of course, it's always possible that he might have given incorrect information).
3. A pity that the Jane LITTERICK who married Joseph has not yet been found in the 1841; Jane would have been ca 20. It would be good if she were found with her parents - though, at that age, she may well have been working away from home.
4. Unfortunately relationships are not specified in the 1841 census. It is tempting to think that James and one Jane are husband and wife, that Jannet, John and Robert & Agnes are their children, and that the other Jane and Hugh might be siblings of James - but that is just guesswork. There is, in the IGI, the marriage of a James LITTERICK to a Jane SINCLAIR in Mochrum in 1830 which is a possibility.
5. Incidentally, ages of people over 15 were supposed to be rounded down to the nearest 5 in 1841 - fortunately for us (as in this case) not all enumerators obeyed the rules!
6. You can find Landberrick if you are interested by searching for it on Streetmap UK. It is also on Multimap but not indexed - you'd need to search for Mochrum, zoom to a 1:25,000 scale, and then look south easterly of Mochrum. I couldn't check out old-maps.co.uk as it was down for maintenance.
