Hi,
I had a look on the 1841 census and found the following.
living in spon end
John Wilson Publican 35
Edward wilson weaver 70
Lucy wilson 30
Thomas Wilson 2
There was also a number of other people living with them including Eliza boyer a servant(15)
As for the Wigston's there wasn't a William, the only ones I can find at the moment is Thomas wigston 69, wheelwright, Charles wigston 20, wheelwright and Ann Cooke House keeper.
Living at the Bull and Anchoor , Rood lane.
Hope this helps.
