Page 205--Rufus D. Stephens
It may seem like this claim provides little detail about Rufus--that it true.
But this is a record from a claim for a horse in the War of 1812. This is an era when there are not large amounts of detailed records and researchers often have to "take when they can get" and maximize it for what it contains.
This claim indicates that at the time Rufus D. Stephens lived in Ontario County, New York. Some of the other records during this era will not even provide a residence at all. So I know that in June of 1817, Rufus D. Stephens lived in Ontario County, New York.
The page on which Rufus' claim was located contained two additional claims from Ontario County, New York residents. Those names may be clues.
I've decided to ask the researcher who obtained these copies for me to look at other adjacent entries in the same ledger to see how many Ontario County residents there were. The name of comrades could be clues.
