The old list on this page also carried Crisp, Echo, Euclid, Findley, Magill, Orton and
\nWillett as separate places. Those are unverified rail-siding or farmstead names with no current
\npopulation, ZIP, or township record traceable to a Census or postal source, so they have been
\ndropped rather than repeated on a guess. Township assignments above are shown only where the
\nplace and township share the same name — a reliable pairing in Iowa’s naming
\nconvention — and left blank elsewhere rather than guessed.<\/p>\n

\nwere available to verify a per-township count, so this table lists each township’s principal
\nsettlement only rather than repeat a guessed number.<\/p>\n
