Wendy,
Back in December 1804, there was a fire in a house in Plymouth, in the market place, where a woman called Mrs Grebbell, wife of a printer called Mr. Grebbell died. There was an inquest into her death, scant details I know, no forenames at all.
I have a note of the inquest, and can send it to you if you want by way of a PM, rather online-if you think it's a relative.
