DEATH OF A CONTEMPORARY OF DR JOHNSON
In our (ie. the Brighton Chronicle) we noticed the death of a Mrs Phillip Vallance, late of 32 West Street. This venerable lady, who had reached her 88th year had been, during her long life, a constant resident in Brighton and was born within 2 doors of her late abode. Her father, also a native of Brighton, was many years a commander in the navy, and served under Sir Edward Hawke in the memorable battle of Mons, Conflans in the year 1729. He lies interred in Brighton Churchyard with numerous descendants. His daughter (the deceased) who became a widow in 1825 continued to reside in her native place, in full possession of her health and strength , until within a few months of her death. She remembered and often spoke of seeing Dr Johnson with Mr and Mrs Thrale, promenading on the Steine, as well as the celebrated and beautiful Sarah Lennox, afterwards Bunbury, and later Napier. She died in London, after 5 day's illness of English cholera surrounded by her family, and to all appearances wholly free from pain or anxiety".
