I have Francis, born Paddington and age 61, in 1911 census at 4 St Albans Road, Harlesden, London NW, a visitor to the home of George Marshall, aged 60, Manager, Land Society.
Francis is described as a Toll Clerk for the Regents Canal Company, and a widower - all of which fits in with earlier findings. And would fit with the probable death entry in 1917 at Cuckfield. One of the Lydias listed in 1911 was at Cuckfield, but there was an IT error and I couldn't open that page. Will try again tomorrow.
George's wife Emma was born at Paddington, maybe a relative, sister perhaps?
