We have a list, provided by Mark, in Barcelona of Wellingore freeholders 1723, Freeholders who took part in an election for a knight of the Shire of Lincoln on 12th February 1723.

Voting Registers and Poll Books can be an important source of information, but remember that prior to the Great Reform Act of 1832 you had to be a property owner to vote. Still, many tradesmen were property owners. Consider this resource:

• Poll Books were used to record the votes that had been cast in an election. They normally have the voters' name, abode, and the place of freehold if different. Some list occupation as well. They are in order by place of abode, not by surname, so you need to have a location unless you are going to go through the whole poll book. These are normally found at the Archives, but the Central Library has copies for 1723-1868.
   

In the UK these are referred to as Electoral Registers or Electoral Rolls. In earlier times they are often known as Poll Books.
