Townlands in the Parish of Cumber Upper

[apthorpea]

I have a query regarding Townland names in 1831.   My family of Reilly's came from the Townland of Kilculmagrandal, my great great grandfather was James Reilly who died at Kinculmagrandal in 1885 supposedly at 100 years old.   Was the Townland of Kinculmagrandal known as the Townland of Coote.
In the 1831 census there is a James and George Reilly registered as living at Kilculmagrandal Townland, Parish of Cumber Upper, Barony of Tirkeeran, Co Londonderry.

In the Londonderry 1831 census returns on Familysearch.  George and James are living at the Townland of Coote, Parish of Cumber Upper, Barony of Tirkeeran, Co Londonderry.

I have tried looking up where the Townland of Coote was but I haven't found anything.  Any help would be appreciated.  Angela

He died at 'Kincull'. Registrar's District Feeny. His daughter Nancy Reilly was the informant.

Looking at Cumber Upper civil parish, the closest named townland is Kinculbrack which is west of Feeny and just east of Claudy.
