Hi Pamela,
I'm not related but am researching Capt D. Cutbush, M.C., of the Middlesex regt, KIA in 1917. I've found out a bit about the Cutbushes from Middlesex, and Douglas's parents William Hickman Cutbush.
I know this is an old post... have you had much success researching your branch of the family? I've found some good stuff on the Free BMD and the online censuses, and the people on the Rootschat.com forum have been very helpful too.
best wishes
Helen
