This course has helped me recognize that I have not searched broadly enough. I should search the records of neighboring counties. Many of my family locations have suffered record losses, so searching nearby jurisdictions may be helpful. I generally have not researched records after my ancestors' deaths. Searching a generation after may be helpful too. I also have a feeling that I have not seen all of the court documents regarding my ancestors. Like he said the probate process, especially, generated a great deal of paperwork. Sometimes all of these papers were filed in several places including bound volumes, loose paperwork etc. I've found probate documents filed in deed books also. I don't live near my ancestral locations, so I can't visit courthouses easily. If I could visit I am sure I would find all of these various court records which can't be accessed any other way.
After studying this course it is clear that studying all documents regarding your ancestors, and their associates, is essential to solving difficult problems. Looking for every minute detail.
