Two red brick tomb chests with stone slab tops and sunk panels on sides. Opposite a stone plaque inset into the chapel wall the two tombs are set side by side. John Penn had the Portland stone plaque acknowledging Gray’s burial installed under the Hastings Chapel window in 1799. The first contains the remains of Thomas Gray, his aunt, Mary Antrobus who died in 1749, and his mother Dorothy Gray who died in 1753. Gray devised the inscription and asked to be buried 'in the vault made by my late dear mother'. He was buried on 6th August 1771. The neighbouring tomb contains the remains of Sara Duckworth, wife of the vicar of St Giles from 1754. She died in 1780. Their son, Vice-Admiral Sir John Duckworth, was in command at the battle of San Domingo which was the last great fleet battle of the Napoleonic wars.
