Thank you all for responding its much appreciated.
The reason I thought she might be in prison is I located the following on another site.
Remmelion Joy Age:31
Estimated Birth Year: abt 1810
Date of Trial:1 Jul 1841
Trial Year:1841
Location of Trial: Kent, England
Sentence:Imprisonment
It could be that the Census was before the sentence or after her release, looks like I need to
find some further information, would I be correct in thinking the quarter sessions will hold this?
Regards
Adrian
