Spent a lot of time today on the name "Ide", which is a good illustration of the wild variation in phonological representation versus kanji for surnames; that's made a para for the paper, but there is one individual case that's proving a thorny one to resolve due to the fact that surname and forename are apparently reversed in the one instance of the name in a city directory, and the fact that the person doesn't show up in either of our community sources for the same year.
