Unfortunately, no records survive that detail any aspect of the construction of the wall; brickmaker, builder and cost are all unknown. The bricks are, however, the typical apricot colour and similar in texture to other bricks known to have been made in Parramatta. Many of the bricks in the wall have impressed arrowhead marks. John Clew’s bricks, distinguished by his elongated heart frog mark and by their speckled markings due to impurities in the clay, were subsequently used to repair the walls. He had a particular affinity for the cemetery and its wall and, when dying, requested he be buried “as close to his beloved brick wall as possible”. His grave is alongside the northern boundary. Unfortunately, I couldn’t find it.
I'm not sure but I think the scratches in some of these other bricks may also be maker's marks.
