Hello Norrie
I just wondered if you had any details on an Arthur Gray Chalmers died 20th October 168, and his brother David Chalmers 1973.
Sorry my information is so limit, both men were unmarried, and I wouldn't be surprised if they are buried with other family, but the only other possible grave location is William Chalmers and Catherine Reid but the headstone you found for them do not mention either of the above brothers.
I have the burial records for their other brothers John and Robert and they are not included in the plot.
Regards
Moo
