I noticed your posting of this baptism - with no further comment. Are you related? The Robert Stock in question was my 6th Great Grandfather.
When looking at the IGI, there is a "report" that this Maria died only days after birth. My own family believes that this might be a misinterpretation. Given that Robert Stock (married to Maria Bambrick) re-married Martha Jackson, it could well be that the Parish Record entry for the death of Maria was in fact the death of 'mother' Maria instead of 'baby' Maria.
