While I did look at the militia lists and did find all 3 names on them, I did not look for pension application files.
I am not related to these folks, such a search would be up to you.
The militia lists did not suggest any connection with the expeditions to Ohio -- so the depreciation pay certificates were for other active-duty service.
I would not expect persons with late 18th-century surname "Best" to be related to persons with surname "Bassett."
By the 1850s rail and steamboats in the Midwest made transportation to and within Ohio a lot easier than it was even a couple of decades earlier.There were all manner of guides and maps being published for travelers and would-be settlers, so there was no need of prior familiarity.Neighbors or kin might have moved there a bit earlier, too, and letters would have been exchanged.By 1859 there were quite a few newspapers, too.
