Searching in Scotlands People to try to find info prior to 1800, but just coming up no results.  Saw a different post that suggested for Sleat in particular there arent any parish records before 1813.  Just wondering if anyone has any suggestions or do I just stop once I get to the early 1800's?
Families I am looking for are 
Kelly - Angus born Strath 1797, his wife Euphemia McLeod born 1800 Strath, 
McInnes, Mary born Sleat 1835, 
Mckinnon, John - not sure of date of birth but his children born 1813-1815 so probably about 1790's and Johns wife Mary Robertson.  
thanks
