Sorry if I didn't make myself clear enough earlier. I believe that Lugmore is the name for the cluster of houses up that lane and not the name of one particular property.
Although a townland is the smallest administrative division, within a townland there are often descriptive names for sections of that townland. For example, in our townland the roadside houses were known as G-- Hill, the clachan behind us was D-- Hill with Bog-- next to them, etc.
On official forms the townland name would mostly be given but other times the 'address' varied with both place names being used in church records (including marriage register), newspaper reports & announcements, letters, and so on.
