With regard to Walton Parochial Cemetery, Liverpool, now operating as Rice Lane City Farm. I work at the farm and would refer you to my FaceBook page 'Rice Lane City Farm - A Personal collection of Photos and Videos.' If you scan down the page you will come across a hand drawn map showing the present layout of the farm/cemetery. There is also a lot of info about the farm/cemetery on the web - Robert Noonan aka Robert Tressell auther of the Ragged Trousered Philanthropist, James Carling, illustrator for Edgar Allen Poe and Ernest Freeman of the Titanic are some of the well-known people buried at the cemetery.
With regard to locating graves, we provide whatever assistance we can, but we are severely limited by a lack of available information. To my knowledge, the original plans and demarcations for the cemetery were detroyed during the second world war bombings.
There are large areas of the cemetery, particularly where mass internments of paupers, TB victims etc., took place, which have no graves stones or markings of any kind. I believe the cemetery was originally divided into four sections i.e. A, B, C, and D, which were further sub-divided into N, S, E, and W sections. However, based on confirmed grave identification numbers taken from War Graves (Listed by the War Graves Commission) located around the site, grave sections range from A through to Z. rows of graves are further identified by letters e.g. front row numbered 1,2,3..., second row numbered 1A, 2A, 3A..., third row 1B, 2B, 3b... and so on.
I believe the cemetery was deconsecreted in the 1970's, but because there are still family graves in use, burials have taken place after that time - The last burial was in 2009.
Incidently, the entrance to the cemetery is via the Rawcliffe Road Gate. The rear Dove Gate entrance on Hornby Road is kept locked for security reason - Don't park on Hornby Road, outside of Walton Prison as any vehicles parked there are regularly broken into.
Due to the difficulty in tracing graves it is strongly advised to phone with whatever info you have before visiting the farm. I am happy to report that we have helped people from across the world with locating graves at the farm. I am also happy to take photos of any grave located and e.mail them to interested persons. You can contact me via the farm on 0151 530 1066, ask for Kevin.
