I believe she died in Taunton and her children were born in Jersey
Where did you get her year and place of death from? She clearly did not die in Taunton in either 1928 or 1929
Where did you get the information from that she lived in Taunton at any time?
I think you need to obtain more positive information on this family. We would not be able to help with any aspect of her life after 1901 as that is the last available census
She did not marry until 1921, and if, as you think, all 3 children were born in Jersey, there is really nothing from a Somerset aspect that is available to help your research at this stage
You need to have a thorough search of the GRO index for her death and confirm for sure that it took place in Taunton and not in Jersey- it's available at your nearest main library or online via an Ancestry subscription or by payment at
