Hello- I was thinking this too. But if the Hiram Imes born about 1820/1823 was part of this household, he would have to be one of 3 males aged 0-10. So his young age wouldn't make him named as head of household. I am guessing that the Hiram Imes on the Scioto census is the 1 male aged 45+ listed in the household. That would make the year of his birth 1775 at the latest. The 1 female aged 26-45 could be his wife, and that would make the children the 1 female 10-16, 3 females 0-10, 2 males 10-16, and 3 males 0-10.
I am wondering if this is the father that was to have moved to Ohio along with Peter, Solomon, and Thomas, and was said to have died en route. It seems, from the age on the census, that this Imes would've been old enough to be their father if he was 45 or over.
The Imes in Ohio seemed quite fond of naming their children after relatives, and there were a lot of Hirams in that family (and Georges and Solomons!). Hiram Imes born 1820/1823 could've been named after his grandfather, the Hiram Imes living in Scioto. Obviously, that's a lot of speculation. This guy has really got me stymied! I wish I knew where the family went by the 1830 census! Thanks!
