As William WILLHAM, he was 14 years old when transported for seven (7) years in 1844, per the Barrosa 2. His trade was "tailor", "native" of Chelsea (UK). He was sent to the Point Puer Juvenile Penal Station, Tasman Penisnsula on arrival.
As William WELLHAM he was granted a Ticket of Leave in 1848 but in 1851 he was reconvicted for assault and larceny, sentenced to three (3) years' hard labour at the Hobart Gaol. William Wellham/Willham was thereafter sentenced to four (4) years for uttering a forged cheque in 1856, and six months with hard labour for absconding from a road gang in 1860, with recommendation he be sent to the prison at Port Arthur (100 kms south of Hobart).
On 7 July 1868, William WILLHAM, per Barossa 2, was sentenced to eight (8) years at the Supreme Court Hobart for larceny. He was 44 years old when he was photographed by government contractor Thomas J. Nevin on discharge in June 1874. If he was 14 years old when sentenced to be transported for seven (7) years in 1844 and 44 yrs old when discharged in 1874, he was born in 1830. His age correlates with his appearance when Nevin photographed him at his one and only sitting with this prisoner at the Mayor's Court, Hobart Town Hall.

The National Library of Australia devised the title for their catalogue entries for this Tasmanian prisoner's mugshot and the other 85 or so in their collection which were accessioned in the 1960s and 1980s from information written in the late 1890s-1900s on the versos by John Watt Beattie and assistants. He removed hundreds of similar 1870s mugshots taken by T. J. Nevin from government records, displaying them for sale at his "Port Arthur" convictaria museum at 51 Murray St. Hobart. They were also displayed on intercolonial and interstate travelling exhibitions in those years on board the fake convict transport Success.

This is a paper copy ca. 1985 made of the original sepia cdv held at the Queen Victoria Museum and Art Gallery. The QVMAG copy was numbered "124" on the front when an inventory was taken there in the 1980s, and it remained there as part of the John Watt Beattie Collection. Other similar mugshots (50) were similarly numbered on the front for relocation from the QVMAG in 1983 to be displayed at the Port Arthur Redevelopment Project at the heritage site of the former prison. Those 50 or so were not returned to the QVMAG, deposited instead at the TMAG in Hobart. The NLA copy shows no numbering on the mount at front underneath the image, suggesting it was copied earlier before the QVMAG inventory in the 1980s and acquired by the NLA from government estrays donated there by Dr. Neil Gunson in the 1960s.
