Janece, The Town Assessor will be the one with the plat maps. It might a good idea to first plot out as many deeds as you need to, until you know "what part of the town" you will need plats for. Hopefully you will learn from the parcel descriptions about one or more landmarks that will tell you this. Each town will probably have more plat maps than you expect. (I needed three for my area of East Haddam, after I knew where to look.) You might ask first if they have a "Key Map" showing what parts of the Town are covered by which plat maps. It's a sort of "map to the maps." In my case, I knew some deeds were for land at the juncture of the towns of East Haddam, Lyme, and Colchester. It was a bit confusing at first because the town line - and the lower boundary of Colchester - shifted north a bit when Salem was created around 1819. Plotting out my Rogers properties in East Haddam, CT, indicated a long 10-acre parcel owned by John Rogers (b 1734) was divided by a local road (nka Dolbia Road).  A historical memoir about the roads and trails of the area made one brief mention that two Rogers' supposedly owned houses across the road from each other.  As I knew who the neighbors were, and that Ralph and Gammon Rogers never owned land in the described location, it was pretty evident that those older two had to have been living on John Rogers' divided property. That was a clincher piece of evidence for me. People didn't necessarily have to been wealthy to have owned property, so we shouldn't assume they didn't.  Sometimes even records for a 1/2 acre of ground and a house could be illuminating. - And even if you don't intend to plot out the properties, the deeds themselves often state family relationships. Deeds are a valuable source of information that is too often overlooked. (Start with the Town deed indexes on LDS micrfilm.) A recent correspondent told me just this week of a deed in Litchfield that proved his ancestor was the daughter of Elisha Borden, who had lived in East Haddam. Her birth had never been recorded there. He was very pleased. Best of luck to you.
