Amongst the monuments in the church of St. Columb Major is one to a John Arundell, once 'senescallus Dñi Regis et verus patronus hujus ecclesiæ, qui hanc capellam fieri fecit.' He died in the year 1400, and stained glass in the windows also commemorated at this date the family. There are also Arundell brasses at Antony East, Mawgan, and Stratton, and a monument at Newlyn East.
They held Lanherne of the Bishop of Exeter by military service, as appears from folio 102 of Bishop Stapledon's Register: it is therein called 'La Herne,' but it was also known formerly as Lanhadron.
Amongst other indications of their early settlement in the county, and of their importance from the very first, it may be mentioned that:
'Rad., son of Oliver de Arundell, of Lanherne, had £20 a year or more, in land, in 1297; and so had John Arundell, of Efford.
'Rad. D'Arundle held a "parv. feo." in Trekinnen.
'Johannes D'Arundle held military feus in Treawset and in Trenbeith, in 3rd Hen. IV. (1402). Also a "parv. feod." in Trekinnen.'
From the Records preserved at Exeter, the following further information, which bears upon the early connexion of the Arundells with the far West, has been gathered; and it is scarcely to be doubted that still earlier traces of their settlement in Cornwall might at one time have been forthcoming:
'Willus de Arundell, canonicus obiit vi. Kal. Maii, MCCXLVI.'
