Individual Details

In the Rapides Parish census of 1820 there appears a John Foreman. The census doesn't give names, but there are data on household:
2 free white males age 10-16
1 free white male age 26-45
1 free white female < 10
1 person engaged in agriculture
There are categories for females of other ages, but none are listed so we can assume that John Foreman's wife is deceased.
So basically we have a Foreman of unknown age (26-45 in 1820) with 1 female child < 10 and 2 male children 10-16.
Analyzing this, if he has two children 10-16, the youngest one could be as young as 10, but then the oldest one would have to be at least 12 in 1820, or born 1808 or earlier...
This would make the children's births (at the latest):
1808 male
1810 male
1812 Female
Assuming the female would have to have been at least 1 year old in 1820, and probably at least 5 years old, places the latest date of her birth as 1819 and probably no later than 1815
