In the 1843 Directory there were “Ale and Porter Dealers” but I cannot find any Public Houses. In 1858 there are “Publicans, Hotels, Inns and Taverns’.
The usually meaning of Huskster is someone selling ale in the street. So it may mean that he went indoors between these dates. However, another meaning of Huskster is someone selling wares from a small booth, so he may have already had a roof over his head in1851, but not where he also slept.
