Way back in this exchange one contributor supposed that Ceres was in St. Andrews.
No, Ceres is a village about 8 miles West of St. Andrews. (It is where I was brought up).
You asked what kind of church the Associate Church would be. At that time there had been numerous splits in the established presbyterian Church of Scotland. I reckon that the Associate Church would have been a congregation of the First Secession. See
http://en.wikipedia.org/wiki/Associate_Presbytery and in the "History" section click the link to "Associate Presbytery".
At one time Ceres had 5 churches, I believe, because of the various schisms and rifts, but I am not sure where the "Associate Church" was. You have got me wondering - I will try to find out!
