George Augustus was an only son who was baptized at St Matthew, Ipswich and educated at Harrow 1871-76 and Pembroke College, Oxford 1876; BA 1879. He was ordained Deacon in 1880 by the Archbishop of Canterbury, as assistant curate at West Malling, Kent and Priest in 1881 by the Bishop of London. His first curacy was at Harlesdon 1883-89 and he was Curate in Charge at Barnes 1889-92. He is known to have been a great traveller visiting every country in Europe and many in Asia, Africa and America.
He became the first incumbent of St Bartholemew's Church, Newton Rd, Ipswich in 1894. This church was built and endowed by Anna Frances, his cousin, widow of Edward Spooner and daughter of John Chevallier and Lucy Cobbold. An inset stone tablet at St Bartholemew's reads: Pray for George Augustus Cobbold, first vicar of this parish, 1894-1915. In grateful memory of his faithful and courageous ministry, this chapel of the Most Holy Sacrament was dedicated June 28th 1925.
The church also contains memorials to Anna Frances Cobbold (1830-1907) and her husband Dean Edward Spooner (1821-1899). A marble pulpit was given, in memory of her parents and husband by Constance S Green and C Alice Cobbold, and a marble font is dedicated to the Glory of God and in memory of John Chevallier and Lucy Cobbold by their grandchildren.
