I should have known better ref copyright as i am an IT consultant..........
However yes i have stumbled on the same thing as you. I can see Cuthbert in 1851 but not 1861. I have managed to find a death for Elisabeth dated 22/03/1855 but i cannot read what it says at all.
Assuming i can post the number of the document it is 197/00 0030 0398 FYVIE if that is of any use, and of course if you need any top ups, i can provide.
