Ah Stan...now you see my dilemma.......

I'm trying to find an Arabella Dooley in 1841 to prove a theory I have about her family but I can't...
1841 - not found
1851 - she's from Ashton under Line, Lancashire
1861 - Ashton, Lancashire
1871 - not found
1881 - not found
1891 - Ashton under Lyme, Lancashire
1901 - Ashton under Lyme, Staffordshire
I suspect that part of the 1841 census I need is missing and that's why I'm having so much difficulty.
