There is a record of a William Chettleburgh born on the 30 November 1837, and subsequent christening on the 3 December 1837 in Saint John De Sepulchre, Norwich to a Sarah Chettleburgh, his father unknown.
Saint John De Sepulchre isn't quite Lakenham as such, although it is on the correct side (South) of Norwich to Lakenham. The streets that it would cover today are around Ber Street (Surrey Street, Mariners Lane, Horn's Lane, Lily Terrace, Foulgar's opening, Thorn Lane, Roen road, Finkelgate) extending to the city walls.
William's first marriage was to Susan Middleton on Christmas day 1858 in St Mark's church in Lakenham. At this time he was a "labourer" and Susan "works at the factory", and they both lived in Lakenham. In the marriage registration her father was given as John Middleton, a "weaver", but his father's entry was left blank. The witnesses were George Dye and Sarah Middleton. Susan was born in Swainsthorpe, Norfolk in 1838.
By the 1881 census they were still living in Lakenham.
Between the three of them they had 11 children, Mary A (~1867), William (~1870), George (~1872), Charles (~1873), Walter (1878), Ellen (1879), Robert Edward (1881), Alice (1882), Phoebe Annie (1883), Anna (~1885), and Edward A (~1890). In the 1901 census there is an another Robert who was born in around 1888, but he is not mentioned in the 1891 census.
He was listed as a general labourer, and then when he was older as a licensed victualler. He was occupying a pub called the Cricketer's Arms in 1891, and is still listed as a publican at this address in the 1901 census (although the name of the pub in not mentioned there). It is likely that he continued in this occupation until at least 1909. The Kelly's directory for 1900 and 1904 list him as the victualler in charge of the "Cricket's Arms" in Lindley Street (or City Road - it is on the corner).
We originally suspected that before that he may have occupied the Champion public house, however this turned out to be a separate (I can't yet say unrelated!) William Chettleburgh.
The 1881 census shows several other William Chettleburgh's along side our William, so we can exclude them from our birth record searches.
One was born on Topcroft in ~1839, one William Norris Chettleburgh was born in Thorpe in ~1839 and one was born in Norwich in ~1836
