Isaac James was the son of Thomas Brush 'the much married' and his third wife Sarah Martin. He was born on 9 November 1819 and baptised on 3 June 1821 at St Luke's church in Chelsea.
At the 1841 census he is living at Commercial Road in Peckham ( which is then described as a hamlet and part of the parish of St Giles Camberwell in the borough of Lambeth) with his father Thomas and step-brother Sidney Cave.

At the 1871 census, age 15, he has gone into domestic service and is a Page at 'Newlands' at Tooting Common in the household of John Kennealy HARPER, a wine merchant, his wife and four sons. They had a resident staff of 8 - plus possibly others in separate houses next on the list. If you want to see a photo of Newlands (from a few decades later) you can look here, but it is spoilt by a logo watermark. It seems the London Boroughs have collections of archive photographs. Instead of just making them available to the public they have set up a company which will sell you an expensive print. I'm not impressed. Remember these are photos on which the copyright has long expired.
At the 1881 census he appears to be a footman at the Bishops Palace of Charley John Ellicott, Bishop of Gloucester & Bristol - with his name given as James. Something which dad spotted many years ago without the benefit of the internet. Dad's comment on this was that there were two possibilities. One that his real name was Isaac James ( as his father had been) or that he adopted a 'Professional' name of James as Isaac might be unacceptable in the custom at the time.

Hedgecroft was the country estate of Baronet Sir George Sutton which was later divided into five separate homes after the war.
By the 1901 census the couple had left service and moved to Shoreham in the north west of Kent, only about 8 miles east of new addington where Emily came from. He had become a RuralPostman. They lived at Ricketts Folly in Halstead Lane about which I can find nothing.
