Answer
The answer is no. Robert James Collier, 1st Baron Monkswell, known by the courtesy title The Honourable Robert Collier from birth until 1886 and as The Honourable Sir Robert Collier from 1886 to 1900, served as the British Attorney General from 1886 to 1892. As World War I began in 1914, he had already passed away in 1900, fourteen years before the war.
