Grassthorpe Chapel (St James) listed under "vanished churches of which the sites are known" (but with no further information). Marnham Chapel listed under "churches of which the sites are uncertain or unknown." (1)
There was an old chapel of St James having land called Priestlands. All were granted by Queen Elizabeth to 3 laymen and the building was converted into a cottage and barn, of which even the site has become unknown. Skegby also had a chapel mentioned in a record of 1392 of which even less is remembered. Is it possible that the two were one ? (2)
The "Doubleday Index" is held by Notingham City Library and examination of this showed the above information came from (4) with a subreference to (5). Here, though Marnham is the main heading the relevant paragraph is sub-headed Grassthorpe. The Enclosure and Tithe Map for that parish bears no small field names but a small plot within the village is noted "Ancient Garden". (3)
