Mr. and Mrs. Timmins came from Louisville, she traveled back to Louisville to get more money for her dig at one point. She had a daughter who was married and lived there as well. Her source for her journal was either her or her husbands grand parents that I would assume lived in Louisville too. The time frame would be the same, she worked Swift Camp Creek in the 1870s-1890 or so. I don't know her maiden name, but she is referred to as Mrs. R.P. Timmins in many articles from the Hazel Green Herald, referred to as Mrs. Rebecca Timmins or lately as Timmons, and locally there she is known as Becky Timmins or Timmons. One article I have she is called Mrs. Perkins...that may be her maiden name as I cannot figure why the author would refer to her as that...and it fits her middle initial. You have to remember Henson's dad was a USFS employee in DBNF and around the Red River Gorge 1950s-1960s roughly. There is a bluff named after him, although the spelling is wrong, called Hanson's Point. That is about all I got in that direction...
Also of note, 1840s might be correct to the original source journal, if you read Prather's book his research shows Swift being a young adult in the mid 1770s and living through the War of 1812 in and around Alexandria,VA as a merchant by trade, but also owned, bought, and sold land in KY multiple times. Some of the land is around Rough River and where Ft. Knox is now...that is just approx. 30miles South of Louisville. No Swift found on record living in Alexandria in the 1760s...that time frame may be another deception to protect finding rights to the mine from the French? (just a guess) and why it mentions French workings in the same area...?
