On this day in 1916, David Green signed up in Midland, Ontario. He stated that he was born on August 10th, 1892 in Deseronto, but census records suggest that he was actually born in 1882, the son of Alexander Green and Catherine (née Maracle), who were both Mohawks. David was living in Deseronto at the time of the 1891 and 1901 censuses, but by 1911 he had moved to Midland and was lodging with his younger brother, Jake, in the town in that year. Jake enlisted earlier in the same month.
Like his brother, David joined the 157th Battalion. His regimental number was 644772. He was described as five feet eight inches tall, with a ruddy complexion, brown eyes and dark brown hair. His service record shows that he arrived in England on October 28th, 1916 and was transferred to the 1st Battalion on November 28th. He joined his unit in France on December 2nd, 1916.
