Hi Frances
Great to hear from you and many thanks for your message.
From further research I have carried out, I now think the lady who died in the flood (12th March 1864) was ANN ETCHELLS (not Etches as previously recorded in all accounts of the flood).
Sadly I have little other information at present but I would love to hear from you (or anyone!) who may be able to help.
Thanks again
Karen Lightowler
