After Harlow New Town was created in 1947 and population grew, the parish was divided in three, with the northern portion retaining the name of Latton.

The altar tomb of Sir Peter Arderne and his wife Bohun is set in an opening between the chapel and chancel and has fine brass effigies.

In 1562 the porch was added by the Altham family, owners of the Mark Hall Estate, and in the late 16th century the tower and the west end of the nave were rebuilt.

Luckily the fire was caught early by a parishioner who was tending to her son's grave, but the church still had to be completely restored in 1965.

The church contains many monuments erected for members of the families who have owned the nearby Mark Hall Estate, including the altar tomb of Sir Peter Arderne and his wife with brass effigies (1467); a brass probably of Sir Peter's daughter Elizabeth and her husband Richard Harper (1492); and an alabaster monument showing the kneeling figures of James Altham, his wife, and 11 children (1583).
