None of the names seem familiar, but I will look into it more deeply, I am pretty good with the names in these time frames so I would be surprised.
I have found at least 2 possibly 3 during this era in Indiana that I can find no tie in's to yet. One was on the Ohio river between Louisville and Evansville, one in Monticello IN close to the IL boarder, and another in Huntington IN, but this one may have had the off shoots to Monticello. I found a May 2010 obit for a Carson in Monticello on line recently, I don't recall the first name, he was 70.
So many Carson's came from Ireland/Scotland during this time, I am surprised there are any left there...LMAO
