Hi,
I think that the other townland should read CARROWCLARE. What I think is Widgeon Lodge can be seen on Google Maps Streetview. Enter Carrowclare Road, Limavady and follow the road to where it comes to a dead end alongside the railway line. Along this short piece of dead-end road it is possible to see a large house with the walls covered in ivy. This is where Widgeon Lodge is marked on the Ordnance Survey Map.
Regards
