This memorial to Robert and Catherine Mawer, in the churchyard of the Church of St Mark, St Marks Road, Woodhouse, Leeds, is Grade II listed.
The sculptor is not recorded, however when Robert died, Charles at age 16 was in the early stages of his apprenticeship, and this is a mature work, so it was probably executed by Catherine.
It was created before Catherine's death, because her memorial was added after Robert's, in a bolder and slightly different hand.
There are additional inscriptions on the gravestone, to Catherine's mother and sister, Elizabeth and Mary Ann Scriven (died 1841 and 1861 respectively).
Between 1987 when the monument was listed, and 2015 when it was photographed by Geograph, the urn and the heads of the two angels were removed.
Historic England describes the monument thus, as of 1987: 
"Ashlar and carved stone.
Shaped podium, a stepped circular console-bracketed base supports 2 almost human-size angels who are draping the inscribed column (surmounted by an urn) with a garland of flowers.
Half the urn has split away."
