Jon, I confuse easily! No worries.
I do have a Thomas Barden, brother of my ancestor John Barden who lived in Burwash (and the elusive Sarah), for whom I have not found a death date. He married Elizabeth Cressingham in Battle in 1792, he would have only been going on 20, but it is possible, given the location. I have assigned a few daughters to him and Elizabeth but not entirely sure of the accuracy. It might be the inquest was for him in 1807.
Went to the Lewes record office decades ago, with my mother, unlikely I will get to the Keep. My mother attended the girl's school in Lewes as a humble scholarship student from Heathfield.
