text: In my opinion, it is correct that both townlands have the same name! The catch is that they are in separate civil parishes or baronies or something. According to the TCD war maps source, they both have the same name and have the correct spelling. (Amazing, since I found 10 mistakes in townland names yesterday in my local area). Other historic sources confirm the spelling of both townlands. So what is here matches the British war maps source, so I think it is correct.
  
  Now to make things complicated! I have seen this kind of thing before (link below). It's easier to see in the editor but the townland "Lugaphuill" looks like it has two parts and I first thought there was a boundary missing along that stream/lake. As it turns out, the TCD British war maps source does show these townlands as one. In my opinion, THIS instance is incorrect and there should be a townland boundary here (along stream) giving another instance of 2 townlands with the same names touching (possibly due to the higher boundaries splitting them). This stream is also a barony/civil parish boundary. Finally, other historic sources show that "Lugaphuill" IS split into two parts here. 
  
  What do you think?
