Re: Cyril & Harold Hurcomb, Harold was my Great-Grandfather. He was an Architect in Oxford before retiring to Devon, and yes, his brother was Lord Hurcomb (Cyril). Cyril had 2 daughters, Pamela & Cecily.
Cyril and Harold's parents were William Hurcomb (1850) and Sarah Castle, and William's siblings were Annie, Ellen, Edward, Jospeh, John, Charles, Henry, Elizabeth and Charles!
