Did Mary Ann Jacobs die in Jersey?

[catmint]

I know that Mary Ann Jacobs was born in Jersey around 1816, her father was Jonathan and her mother Ann.  In 1841 she was living in her mother's household in St Helier. In 1851, 61 and 71 she is found living in England in Bath.  ( In 1871 she is referred to as Mary Ann Jefferies)  After that I can't trace what happened to her.  I have no evidence for her death or name change due to marriage in England and wondered if she went back to her place of birth, Jersey.  I would be grateful if anyone can look up death records for Mary Ann Jacobs or Jefferies/ Jefferys after 1871.
Any information regarding her baptism would also be appreciated.  One of her children was brought up Roman Catholic and I wonder if Mary Ann was an RC.  Any help much appreciated.  Thank you
