My Great Grandfather, Albert Henry MacDonald was there too serving as a cook in the Canadian Army Medical Corps. A railroad man by trade, he joined on 24 May 1916 in London, Ontario, aged 31. I never knew him as he died in his 50's. My Grandfather told stories passed on to him about the cooks making huge caldrons of mutton, (with hair and all), and no one in the family ever touched lamb for generations afterward! I have his picture, discharge certificate, cap badge, service medals and veteran pins framed on the wall here in my office.
