Lupo a.k.a. matt at lupo dot com Matt: Those counted in the 16-18 age group are a subset of those in the 16-26 group. IOW, if there were one in each group, it would represent only one person. In your case, there were three males aged 16-26, one of whom was aged 16-18. An excerpt from "Instructions to Marshals" for the 1820 census: "Those, for instance, between 16 and 18, will all be repeated in the column of those between 16 and 26."
