Hi Zelda, this is the adjoining plot, so most probably the same family. This stone is very badly eroded unfortunately.
The inscription was - "James Muir died 14th October 1879 aged 84 years. His son Daniel died at Shawlands, Glasgow 28th September 1903 aged 66 years, husband of Mary Douglas. Their daughter Mary Douglas died 20th April 1908 aged 42 years".
