Many thanks for your rapid response. With regard to the Bardolphe arms I have just come across the following, which you may or may not have seen:
"The History and Topographical Survey of the County of Kent: Volume 4 (1798), pp. 2-16.
HOO, ST. WARBURGH.
King Richard I. exchanged the manor and hundred with Hugh Bardolf, for the honour of Bampton, in Devonshire, which had been forfeited to the crown by Fulk Paganel, or Painel, as he was usually called, to whom it had been given by king Henry II. (fn. 2) He was a younger son of William Bardolf, of Stoke Bardolf, and bore for his arms, Azure, three cinquefoils pierced or, as they remain on the roof of the cloisters of Christ church, Canterbury. He died without issue, (fn. 3) on which this estate of Hoo became vested in the crown, whence it was granted, anno 17 king John, to Hubert de Burgh, (fn. 4) then chief justice of England, and afterwards earl of Kent, on whose disgrace it seems to have become vested in Henry Grey and Hugh Poinz, in right of their wives, two of the five nieces and co. heirs of Robert Bardolph above mentioned, in separate moieties."
With regard to the seal used by Robert Davie of Canonteign on the 1614 Combe Lancey lease, it is simply the 1594 "Azure three cinquefoils 2 and 1 Or, on a chief of the last a lion passant Gules", ie no impalement/quatering etc. Confirmation that these are the plaster arms on the overmantel at Canonteign Barton would I think clinch the fact that they were used by the extended family rather than just by John of Exeter and Creedy. Canonteign Barton has apparently recently changed ownership and access to these arms may not be straightforward.
I will visit the Record Office sometime in the next few weeks and see whether I can access the Pedigree.
With regard to my particular study on the manor of Combe Lancey I would be interested in the details of Robert Davey's IPM, as I am trying to ascertain whether it was he or son Gilbert who acquired the manor - and if so from whom.I am aware that it was held earlier by the Pollards who acquired it from the Cornu-s who acquired it from the de Launcells. The Pollards may have passed it to the Wilfords (Merchants and Clothiers of Exeter)and from them by one of many possible connections/marriages to the Davies, or by simple purchase!
