It is difficult to estimate accurately the numbers attending his congregation. If 300 communicants were present, then many others must have been attending also, including the children of the communicants. According to the statistics compiled by Dr. John Evans between 1715 and 1718, the number of Presbyterian hearers in Chester numbered 1,000. For the whole of Cheshire in the early eighteenth century, eighteen Presbyterian congregations existed, with 8,000 hearers. This meant that, out of a total population for Cheshire of 111,700, the Presbyterians accounted for 7.25%. By comparison, the General and Particular Baptists had only seven congregations, with 330 hearers, this number being only 0.3% of the total population.
