In searching the Hummert name in Warrenton or Truesdale, Warren County, Missouri, I can find nothing, either on a census record or elsewhere. Searching Warren County, Missouri history there is no account of any camp in Civil War times. However, I did find a profile of Brigadore General Lewis Merrill and interestingly his wife's name was "Annie", i.e. Annie Rhoda Houston. Perhaps Camp Annie was so named after Merrill's wife?
