Pearsed pride

I feel duty bound to report on a clue which was just trying to get itself in my head.
Ann Pearce is living with her father, aged 31, in 1841, or so it seems.
Here is the census entry:

1841 Church Town Lanteglos-by-Fowey HO107/153/9 fo19 p7
William Pearce 70 farmer, Ann 31, Susan 30, Edward 21, Emma 20, Fanny 15 (all b Cornwall), plus servants

It turns out though that I wasn't reading the census entry correctly.  Ann had actually gotten married the previous year to Thomas Pearse, of Bodmin, and sure enough they are living together in 1851.

You wouldn'a thunk it, but Ann Pearce was Ann Pearse in the 1841 census.....
