Just another follow up on the responses to my isonymy poster presentation: one comment that came up a few times was from both students and professors was that they would love to use isonymy in their own work, but since they were working with a single population it was impractical. In those cases, I recommend two articles by Lasker and Mascie-Taylor dealing that use isonymy at very small scales, including between and within households.
