Wanted information about Elizabeth Jackson

[Grumpy2]

I am looking for Elizabeth Jackson born 1816 who married Leonard Jackson in 1840. She appeared in census 1841,1851 but I cannot find her in the 1861 census.She is in the 1871,1881 census. She died in 1882 and her husband died in 1893.They had 5 children. I want to know if anyone has any ideas as to what could have happened to her in 1861 to 1871. They lived in Lancashire and were born there.
Any help would be appreciated.
