There were some hospitals even at that time. Unfortunately I don´t know that area at all, so I can´t guess where a hospital might have been. What about her birth record? It was not a rule, but sometimes the person who wrote the record made notes about deaths there - especially when someone died in another parish. Were her parents still alive? Maybe she got sick and her mother took her back home to take care of her. Or a married sister, something like that.
