"My father, Pleasant Adams Hackleman, was the oldest son and born in Brookville township, Ind., Nov. 15th, 1814. He was an ambitious boy and determined to have an education. He attended the country school three months for three winters and after that he studied at home in the family kitchen by a pine knot blaze in the big chimney. He was a student always, and deserved great credit for his good education, it was so thorough and so practical. He studied law after he was married, having taught the country school in the neighborhod three winters, one before his marriage and two after." (pg. 208)

"my father taught school two winters after his marriage, then removed to Brookville, Ind. and went into the law office of John A. Matson, who was afterwards governor of Indiana." <-- there was no John Matson who was governor of Indiana, according to Wikipedia. "Governor Matson took great interest in his young law student, and gave him great encouragement. He was admitted to the bar in one year, such awas is unusual progress, passed his examination with great credit, then decided to move to Rushville where he went into practice and was very successful. His first case was a revolutionary soldier's, who had been trying for years to secure a pension and back pay." (more available but not copied to this record)
