The last baptism to take place at Old St Lawrence Church was on the 21st February 1773 for Susan George.[3]
New St Lawrence Church was consecrated in 1779.
Graveyard
Although Lionel Lyde and his wife Rachel are commemorated at the new church,[4] the old churchyard remained in use. Burials include Rudolph Lambart, 10th Earl of Cavan (1865 – 1946), whose maternal grandfather was rector of Ayot St Lawrence. Earl Cavan was a Field marshal and his resting place is registered by the Commonwealth War Graves Commission.
Although the Earl was not a casualty in the normal sense of the term, the entry refers to the "memorial to the casualty in the form of a large 7' red granite celtic cross".[5]
