Patrick and Alex were both employed by The Great North of Scotland Railway and are commemorated on that Company's War Memorial at Aberdeen Railway station. I will be at this site on 11th to lay a wreath for all the employees of the GNSR.
All three brothers also appear on the New Elgin and Ashgrove Memorial in Elgin.
