The church was the centre of early Thrale life, as the closest parish church to early Thrale farms.
St Leonards Church, Streatham, was the church attended by descendants of Ralph Thrale during the time that they lived at Streatham Park. The Thrale family vault was under the south aisle of the church and the covering slab is still there. However, the family remains were removed to the new catacomb at the time of the rebuilding of the church in 1831-2. The remains are still there and were respectfully filmed by the BBC in 2001.
