There is a wall tablet in the south transept of Conington church with the inscription: "Near this place are deposited the remains of John Heathcote Esq.
After a residence of 38 years at Conington Castle he died May 1838 deeply and justly lamented by his relatives, his neighbours and his friends.
His son John Moyer Heathcote has caused this stone to be erected as a token of appreciation, gratitude and esteem.
"[5] Mary Ann Heathcote died on 27 July 1854 in St George's Hanover Square London and was buried on 2 August 1854 at All Saints church Conington Huntingdonshire.
Looking for that blessed hope, and the glorious appearing of the Great God our Saviour Jesus Christ.
