Camden County lays to the east of Benton county. The land Hugh bought from the Government in 1859 was just over the Camden and Benton line. It was 160 acres. 40 of that purchase was in T40N R20W Sect34. 120 acres was in T40N R20W Sect27. Sect 27 lays directly over Sect 34 so the whole parcel was connected. It was where I described in the other post near Lively Mo.
I found Hugh Allison had patented land in Camden County twice. Once in 1853 and once in 1854. 40 acres each time. I can go back and look the location up for you if you want. I also found Hugh patented in some other counties but will have to recheck that. You are on the wrong side of Benton County. Knobby Creek ran up the east side of the 160 parcel and looks like there was a nice big spring on or very near.
Too bad "Clay Allison" was not there when the ruffians attacked the family. He would have killed the whole bunch.
