I would suggest you get this death certificate from the state of KY to be absolutely sure, and use the name Seal as well as Seals. The Seals were concentrated in Hancock County, but were in other counties as well. Some used the Seal spelling, others the Seals spelling. Since both Jesse and James were often used in this family, unless you know the siblings names it might be difficult. His obituary might give the names of his siblings, but his death certificate would be your first step.
