Hi...My gggrandfather died in Beaver Co. in 1839. His death is "Registered" and listed on the Will-Book Index. I guess not all deaths were registered. He died intestate, so there was no will, but just the registration. Try looking in the Will-Book Index for Beaver County. Hope this helps. Marcia Mann Duggins in Florida.
