Evelyn St George Curtis was born on 23 April 1882 in St Pancras to parents George Byron Curtis, a journalist and author, and his wife Caroline. The family had been living for over ten years at 70 St Augustine's Road, St Pancras and were recorded in 1881 employing three servants. Evelyn had three older siblings - Frances, Beatrice and Stanley. By 1891 he had a sister, Linda, two years his junior and the staff numbers had reduced to two. Stanley and his brother attended Dulwich College and from College records it shows that the family lived in Cedar House, 27 Herne Hill for a period during the boys' education. By 1901 the family had moved to Airlie Gardens Kensington where the five adult children resided with their parents and five servants. No occupation was given for the family except George Byron who was still a journalist and author. By 1911 the family had moved once more, this time to 110 Riverview Gardens, Barnes. George is recorded as a black and white artist and was 28 years old. A letter from George's sister Beatrice written in 1920 provides more details about his life:

"Evelyn was an artist and had a good many pictures published in magazines, in stories which he illustrated. He was very clever, and I believe would have had great success. He gave it up and enlisted in the 10th Middlesex in October 1914 and was in that regiment until he obtained his commission in January 1917. He was sent to the East Coast and was at Yarmouth when it was bombarded. He went to France on the 27th February 1917 and went into action almost directly he got there, where I cannot say. We knew very little of his movements when he was in France. On May 3rd, 1917 he was in a big battle, near Arras, as far as we were able to find out, and when last seen had been slightly wounded in the arm. Since then nothing has been heard of him. We had a very nice letter from his Major saying he could tell us nothing more than that he had been reported "missing" and also saying what a popular officer he was."

George was presumed to have been killed in action. He had been serving as a second lieutenant in the 7th Battalion of the Middlesex regiment. He would have been 35-years-old when he died and had earned the British War and Victory medals. He left over £670 to his elder sister Beatrice and is remembered on the Arras Memorial, France.
