The 1911 Great Britain NAPP data comes at the level of parish (variable parishgb_1911), which runs from 100001 to 111530 and then 999999. I am looking for a map to match these parishes to. Centroid coordinates of parishes would help, as would a shapefile. Names to these parishes may also help me to match them.
One thing I am aware of, seems to be a dead end: I found a UK 1911 parish map here: visionofbritain.org.uk, but indicators on this shape file do not match with the codes in the NAPP data.
Many thanks and best wishes.
