Hi Colmn,

I don't use the location from logainm to match up to OSM objects.
Instead I use the hierachy. So if civil parish X is in barony Y in OSM
and logainm, and barony Y has a logainm:ref of 123, and logainm only
has one CP in barony Y with the name of "X", then we can match it up.

Also, at the moment, I've only match up counties, baronies, civil
parishes and townlands from logainm. I haven't let done any of the
other things like "population centres" or bridges.

Never doubt that a small group of thoughtful, committed citizens can
change the world. Indeed, it is the only thing that ever has. Margaret M
