[OSM-talk-ie] Query on tracing townlands and dealing with changed lake levels and new boundaries

[Killian Driscoll]

I guess the point is 'Inishfale Island' was never an official townland (at
least the name doesn't turn up on the online databases, I don't have access
to the print copy): the sites and monuments record uses 'Inisfale Island'
as the name. Is/was Beggerin Island a townland?
