I comment inline some points I didn't answer, and more on the A, B,
C... point.

If sure, I would move it to that isolated_dwelling too.

Good. And that's why I added to the workflow wiki 2km on all
directions when downloading the OSM data: "Download from OSM an area
around each of those nodes. 2 Km radious would be more than enough."

Although I answered to this before, I would add that having one single
name in several nodes, with 1, 2, 3... or A, B, C... or I, II, III...
added to the end to differentiate them is quite common in many
countries in Africa. You can find many of them in Central African
Republic or Nigeria, as just two examples. I again would leave all
those nodes separated as they are, and not condense them in one. I
can't assure you that they are automatically produced, but it could
very likely not be the case.

Cheers,

Rafael.
