Janet,
Did Jesse ever live in Fayette County? There is a Texas Confederate Pension Application for a Jesse Blackwell in Fayette Co., TX. Texas Confederate Pensions generally have a wealth of personal information. Recently, I ordered one that listed all of the doctor's visits to the man after he had become a pensioner, his death, funeral and burial arrangements including providers of services and cost. You can never tell what is in a pension application file, but sometimes you can really hit a goldmine.
