The best way to get to know his personality is by reading the record of the Richmond Ratification Convention of 1788, which is in volumes VIII-X of The Documentary History of the Ratification of the Constitution.
Avoid Wirt’s biography. I don’t much like Beeman’s either. William Wirt Henry’s is pretty good, and it includes several letters, etc. Far the best is A Son of Thunder by Mayer. It gives you all the important details of his life and a clear impression of his personality. It also captures his principles.
If you want more after reading those, let me know.
