The second son, Charlie, who was a lieutenant in the King's Own Scottish Borderers, was killed at the Second Battle of Gaza in April 1917. The eldest son, James, who was a captain in the Royal Fusiliers, was shot down and killed on 21 September 1917, and the deaths made Law even more melancholy and depressed than before. The youngest son, Richard, later served as a Conservative MP and minister. Isabel married Sir Frederick Sykes (in the early years of World War I she had been engaged for a time to the Australian war correspondent Keith Murdoch) and Catherine married, firstly, Kent Colwell and, much later, in 1961, The 1st Baron Archibald.
