Not much, really. One of the other Huffer researchers had given me Daniel's first name and Letha's maiden name. And told me that Daniel had disappeared while on a hunting trip. No body ever recovered. Very sad. Perhaps a bear got him? Or he fell in to a creek with a swift current. She never remarried, and died in 1898. Would love to find more, but I don't know if any other documentary data exists. And I'm in CA.
I think, but can't prove, that Letha's father was Pleasant Austin, b. 1798. I thought that his name may have been used to name Letha and Daniel's son Pleasant A. (I don't know what the A is for, Austin does fit, but is just a guess.) From the data I have found in the censuses on Pleasant and Sally Hicks Austin, there were two daughters in the censuses as yet unidentified and Letha fits the age very well, of one of them. Again... I'm in CA, so I don't have local documents to look at, and I think ... maybe some old church records or Bible records or local county sources, if they still exist, is what it's going to take to find more, unless some stories have been carried down.
The line I'm researching is through Pleasant A., William A. and Halton Huffer.
