My face is RED !! I knew this at one time, and just didn't think about it when I was "guess-timating" the age of William Townzen from the 1820 census of Stewart co TN!
William Townzen, shown as age 16/26, but with a male also shown in the 16/18 column, CAN ONLY BE AGE 16/18, (B:1802/1804) See below:
Excerpt from: “ ~ The Census Book ~ A Genealogist’s Guide to Federal Census Facts, Schedules & Indexes”, by William Dollarhide
“A special consideration unique to the 1820 census form asks for all males 16-18 yrs of age, and in another column, all males 16-26 yrs of age. The purpose of these two categories was to determine the number of young men in the U.S. of military age. If a male was shown in the 16-18 column, he would ALSO BE INCLUDED IN THE 16-26 COLUMN. Further confirmation of this can be found in the 1820 instructions to the U.S. Marshals, which read as follows: It will be necessary to remember, that the numbers in the columns of free white males between 16 and 18, will all be repeated in the column of those between 16 and 26 , and MUST NOT be added to the general aggregate total for this household, which would result in the same person being counted twice”
This creates another puzzle! William in this 1820 census has 2 males under 10, and 1 female under 10 - How on earth did he have 3 children by the age of 18 ? Ok - so it IS possible, but highly improbable. Does he have someone else's children living with him? Whose children? Did he have twins? triplets?
