@PolyGeo that sounds like an interesting little project for when you have the time. I had a quick look at the 1838 tithe records on TheGenealogist and "Thomas Hitchcox Junior" owned over 50 acres split across more than a dozen plots at the time, which looks like a fair match to your Thomas. The record includes plot names, and they can be shown on the tithe map, which might be helpful. Ping me if you want more info.
