The return from the Primitive Methodist society in Carnkie in Illogan parish to the 1851 Census of Places of Public Religious worship was completed by John Sharpe, the Primitive Methodist minister of Chasewater New Town. It gives details of attendance and capacity. On Census Sunday, 47 attended the morning service and 70 the evening one. There was no Sunday school.
The Return uses the name Carnkie rather than Higher Carnkie. However, it dates the erection of the chapel as 1830. Jo Lewis confirms that there is a Kresen kernow document relating to the balance of a loan being paid by the Prims in March 1830 which would confirm the 1830 date in the census as a start date for the chapel
