That would be Samuel Earl McClatchey. I would very much like any information about him as well. His parents are unknown to us, but we believe he is an offshoot of the same family as Adolphus Patton McClatchey.
What information are you able to offer, and how can I get more?
I have queried Nara regarding McClatchey records, but did not find him, if he's mispelled under 'McClatchey' that would explain why :-(
