The 1817 reference.
Page 137 (shown below) contains the actual reference to Rufus D. Stephens who was paid in June of 1817 a total of $80 for a horse.
The problem is that this reference contains no additional information on Rufus--where he lived, where he filed the claim, etc. This book was obtained in digital format on Google Books and can be referenced here.
While the name of Rufus D. Stephens is not all that common, there could easily have been more than one person with that combination of first and last names. At this point, I'm trying to determine if this Rufus is the same one who was referenced in an earlier blog post. I'm also glad his name is not John Smith. We're working on a brief blog post about our methodology on trying to determine if these men are one and the same (and on establishing their connection to the actual person of interest).
There may be more information on this claim than appears here--maybe. On our short list of things to do is determining if there is additional documentation for Rufus' $80 claim.
