Thank you for all that great information. I have contacted the brother in my family who has done the most research on that part of the family hisotry. Hopefully he will be able to shed more light on the number of people killed.
Re date: All I know is 1863.
Re: # killed -- I know for sure that Hugh and his wife Sarah were both killed. I do not know the names of the children killed (the ones still living at home were all teenagers or 20s.) The Camden Co. Deed Book 7, p. 67, dated August 11, 1886, lists as "heirs at law of Hugh Allison deceased" only five of his nine children. Missing are the names of three daughters (ages about 20-24 at the time of the murders) and one son (age 16 or 17 at the time of the murders.)
Re: location -- Hugh Allison bought land in 1859 at Township 40-N, Rnge 20-W, in Benton Co. The purchase was registered at the Warsaw Land Office. Hugh also sold land to his son-in-law [John Howard]in the same area, sect. 36, Tnp.40,Rng 20, Benton Co, 1859. I believe that puts him in the western part of the county, not far below the Osage River and not too far from Warsaw.
Hugh Allison had seven nephews (one of them was my ggf) living in the Camden Co. area. They all served in EMM units, however two of them (Newton and James) also were in the MSG 6th Div, Confederte unit. Those two were captured at the Battle of Wet Glaize and Linn Creek in Oct. 1861 and sent to Rolla. Later they were in EMM units. Even though they were in EMM units, I think their loyalties lay with the CSA. I say this because many years later, my ggf named one of his sons Robert E. Lee Allison.
