It looks like these are (or were) on the site of the cottages opposite Arnold Clarks showrooms on the A701 road, just south of Clarencefield Road junction. Here they are on an 1855 map.
Your gg-grandfather must have worked with mine who also was a stone-mason in the quarry in1841, though he lived in the village itself.
