Creffeild's marriage settlement described him as being of the Inner Temple, and thus it can be surmised that he was at that time already employed as a barrister.
In 1717/18 the couple moved to a new house in the centre of Colchester, Hollytrees, which had recently been constructed for Sarah's aunt.
[2] At some point he also purchased Mose Hall in Ardleigh,[3] where his father already had a substantial estate.
Creffeild soon became a justice of the peace for the county of Essex and an Alderman of Colchester.
[4] Sarah married again after his death to Charles Gray, but, since they had no children, the estates reverted through Ralph's surviving children, Peter, Hannah (later married to George Wegg, another wealthy landowner at that time), and Sarah.
