Philip Hamburger, Liberality:

I can't copy and paste from this PDF text. But Hamburger, whatever issues one may have with his analysis and conclusions, is one of the most meticulously learned legal historians of the American Founding period. There is a treasure trove of info in the above linked piece, full of terms that one could put into a search engine, googlebooks and so on, to deliver a wealth of primary sources. Eliphaz Liberalissimus, for instance.
