David Ramsey Acheson, and eight of his children, are listed in the 1850 Census here: Ohio, Guernsey Co., Knox Twp. Image 13 of 19, Page 483. Guernsey County was dervived, in part, from Muskingum Co., OH.They initially emigrated to Muscatine Co., IA, with eleven children in about 1851 where they farmed near David's brother,Humphrey.
The census-taker misspelled the name Acheson, as Achison.
David's wife, Elizabeth Law also contracted cholera, but she survived. Their youngest daughter, Margaret, died in the epidemic, but I don't believe that William died from cholera, even though he died in 1854 (according to my diary account from Mary (Acheson) Baird's family (who was David & Elizabeth's daughter.) Importantly, they were at the home of David's brother, Humphrey and wife, Elizabeth Betsay Hunter, who both died from the cholera within a few days, also.
The Acheson orphans (16 total by my count)then went to live among the remaining siblings of David and Humphrey that had settled in Iowa. These would have been the uncles of the children.
Elizabeth (Law) Acheson had three children 17-21 years old at the time, and the rest of her children were minors.She lived with other family members in Louisa and Washington Counties until her death.One son, Anderson David (A.D.)Acheson, served in the Civil War with three of his cousins, then returned to Washington County where he prospered and farmed until his death in 1918.
