Apart from different name spellings, the first has completely missed out niece Ellen aged 3yrs...
The first one usefully gave the whereabouts in Ireland.

Mother Elspeth PRATT is missing from the first, and 12yr old daur Margaret is as Head....
(Ancestry made it more confusing on both of these...
they've got the Pratts & Wilsons as as members of the
previous household...

The surname of William differs quite a bit, and likewise his occupation....
But it's a transcription, and capital letters "L" and "S" can look very similar.
Seems the surname is actually SEAGARS (from IGI).

The above 1881 census 644-2 Ed 51
pages 1 - 23, are
also as 644-2 Ed 51
pages 24 - 47.
Thankfully they didn't all have differences like the three more extreme examples above.
