[OSM-talk-ie] Townland Boundaries

[Patrick Matthews]

It's a barony boundary - baronies include open water like lakes and large
rivers whereas townlands generally only go as far as the foreshore and
don't include parts of the lake (certainly not the larger lakes or larger
rivers, although the dotted lines indicating townland boundaries will run
through smaller lakes or rivers.

Civil parish boundaries aren't shown on post-1898 maps except within urban
districts and boroughs. You have an issue where townlands are divided
between civil parishes - if the two parts of the townland were in different
DEDs then the boundary continues to be shown (there are a number of
examples in Wexford where you have two adjacent townlands with the same
name but with (E,D. X) and (E.D. Y) as suffixes. If the two parts of the
townland were in the same DED then there is no indication on the map,
although the 1911 Census reports will still list them separately. (You can
also have "false positives" - there are two townlands in east Cavan called
Corravilla, one in Shercock parish and the other in Knockbride parish,
which are distinct and have different postal addresses but which happen to
fall in the same DED and so are marked as "Corravilla" and "Part of
Corravilla".)
