<<It is merely a listing that helps to narrow down the numbers of young men between the ages of 16-18. My source is "The Source, A Guidebook to American Genealogy.">> Yes, but why would they want to do that? And assuming there was some purpose, why did they count the 16-18's again among the 16 -26's?? By the way, I've noticed that census takers often did not follow the instruction: "Those, for instance, between 16 and 18, will all be repeated in the column of those between 16 and 26." Sometimes when I've seen a single 16-18 next to a single 16-26, they are the same person, and sometimes they are different. TC
