If this is the family in 1861, Daniel Jnr is 3, rather than 1:
386/A 11/ 12 Muthill Perth
Daniel 32
Catherine 24
Peter 6 FISHER Peter 1954 386/A 30 200 Muthill
Ann 5 FISHER Ann 1855 386/ 66 Muthill
Daniel 3 FISHER Daniel 1857 386/ 67 Muthill
William 1 FISHER William 1859 386/ 89 Muthill
The 1871 328/B 2/ 1 Ardoch Perth, same except for no Ann and addition of:
John 5 FISHER John 1866 386/A 12 Muthill
1881 328/B 2/ 1 Ardoch Perth, addition of James 7 and a Daniel 2, no father.
On the 1891 328/B 2/ 9 Ardoch Perth, both Daniel’s are shown as Donald. I’m thinking that the 2 year old on the 1881 is Donald and the Donald on the 1891 is your Daniel at age 31.
Please note I am only seeing the indexes on SP and not the census pages.
If they followed the naming pattern, this could be the birth of Daniel Snr:
FISHER Daniel PETER FISHER/JEAN PHILP FR4283 (FR4283) 13-12-1829 644/1 320 629 Glasgow
His death:
FISHER Daniel 52 1881 328/B 4 Ardoch
Two possible births for Catherine:
DRUMMOND Catherine PETER DRUMMOND/ANN MCULLOCH FR732 (FR732) 13-9-1836 386/A 30 166 Muthill
DRUMMOND Catherine JAMES DRUMMOND/JANET COMRIE 18-7-1836 386/A 30 102 Muthill
Her death:
FISHER Catherine 62 1899 328/B 5 Ardoch
