Erin,
Anne Walsh died on the 5th and was buried on the 8th in Overleigh, probably in a communal grave in G section between G922 and G1024, although her name doesn't come up on the Overleigh database.
If you check the burial register for St Werburghs and look up the names either side of Anne, they do come up in the Overleigh database hence my deduction above. It is very unlikely the grave will be marked as it will probably be communal.
You may have to go back to the source and check with the Record Office to see if it was missed off the database accidently in case there is a grave reference.
