Theo van de Bilt has been researching people of colour living in the Sawbridgeworth area in the past and he found George Ottea who worked as a butler at Terlings Park in Gilston. He was working there in 1891 according to the census. There are fascinating stories of how he got there, his previous employment in London and how he met his wife. He was highly thought of by his employers and is buried in Gilston churchyard.
