Perray Avenue is a short street attached to the northern side of Hawthornhill Road. About 350 metres to the west are the similarly-named Perrays Way, Drive, Crescent, Grove, and Court.
About 600 metres to the north-west of the point where the photograph was taken is a small square of woodland (
NS37397659) called Perrays Wood (visible on the left in
NS3776 : Farm track); this makes the origin of all of these street names clear.
The same
NS3776 : Perrays Wood is mentioned in David Murray's book "Old Cardross: a lecture" (1880), where it is described as "the wood about halfway between Kellochy and Hawthornhill" (Kellochy, now long gone, was at
NS36757724; for Hawthornhill, see
NS3776 : The former site of Hawthornhill Farm).
The same work adds that "The Perrays" were "the two fields on the north of Hawthornhill, on the east and west of the road to Ardochbeg" (on which, see
NS3777 : The ruin of Ardochbeg).
