[1] He continued his studies in Paris, where he met his first wife, the noted sculptor Alice Meredith Williams.
They married in 1906 and lived in Edinburgh where Morris worked part-time as an Art Master at Fettes College and as an artist and prolific illustrator of children's books of myth, folklore and history.
He served as an officer in the Welsh Regiment and The Royal Engineers in the First World War,[2] and during this time drew many sketches of trench life and battlefield destruction, some of which were worked up into paintings after the war and now hang in regimental museums and in the National Army Museum.
Morris designed the metal frieze of naval and military figures, modelled by Alice, for the shrine of the Scottish National War Memorial at Edinburgh Castle.
[2] Williams worked in landscape and genre painting, stained glass, engraving and illustration.
