In the chapel of St Nicholas in Westminster Abbey is an altar tomb of Purbeck marble to Nicholas, Baron Carew. It is placed against the wall under the monument to Lady Fane. There is no longer any inscription and the three shields have gone. In a guidebook to the Abbey of 1600 the inscription is given and this can be translated:
Pray for the souls of Nicholas, sometime Baron Carew, and the Lady Margaret his wife, daughter of John, Lord Dinham Kt. Which Nicholas died the 6th day of December Anno.Dom. 1470 and the aforesaid Lady Margaret died 13th day of December 1470.
He was feudal Baron of Carew in Pembrokeshire. He was possibly a son of Sir Nicholas Carew who died in 1449 and had five sons. The family also had branches in Devon and Cornwall.
