Bevan is listed as working from 2 Pier Terrace and 2A Pier Terrace, Lowestoft in Kelly's Suffolk Directory 1875/1873/1883/1888/1892/1896 and White's Suffolk Directory 1885/1892 as well as Huke's Directory of 1892.
In G. S. Cook's Directory 1882, he is listed as working from 3 London Road South, Pier Terrace.
According to Robb/Godfrey, glass negatives from Bevan's studio passed into the hands of the Jenkins family, when they took over the premises. They survived in the Pier Terrace basement until lost (along with Jenkin's plates) in the East Coast Floods of 1953. Some of the Bevan archive may, however, have already been lost in the earlier floods of 1897. The Robb/Godfrey correspondence dates the Bevan studio to 1874-1896.
According to the Lowestoft Journal, Bevan was born in Ipswich, Suffolk, in 1852 and arrived in Lowestoft in 1874, when he took over the photographic interests of William Reed and of Delaney & Co. His wife, Clarissa (whom he married in 1876), was from Lowestoft, and they had three children. He was appointed official photographer to the mayors of Lowestoft and in 1877 (shortly before her death at the age of 103) he photographed Lady Pleasance Smith, daughter of the Lord of the Manor of Lowestoft and wife of the Linnaean Society’s founder. Bevan sold the business to Harry Jenkins in 1898 and died in 1927. Reference
Bevan, J. of Pier Terrace, Lowestoft was listed in Harrod's Norfolk Directory, 1877. I think this "J" is a typo. It's the only time in my research a J. Bevan shows up.
