I doubt if there is much information about domestic servants as a lot of young women at that time went into service. Some lived in and others lived at home, going to work every day.
My only other option i guess is to get a copy of the death cert.
That is your best option, although it won't tell you where she is buried. Unless the family were well off, and if she was a servant, they probably weren't, there may not be a headstone, so you won't find her in the cemeteries. Your only other hope is the Parish records which may show the burial.
Were her parents or any family still living in Bletchingley when she died? If so, her body may have been taken back there for burial, especially if there was a family grave.
