My ancestors - surname Colquhoun - lived at Hole Farm, Old Kilpatrick until sometime between 1851-61. Has anyone come across any headstones for the Colquhoun family? The deaths I know about are my Grt Grt Uncle, Robert C, died 1839 aged 2 and my Grt Grt Grt Grandfather, Walter C, died in 1816 aged 65. There could be many others too. Thank you.
