The older Joseph Koger would have been about 55 tears old in 1760 if he had been born in 1705 and wouldhave been in South Carolina about 25 years.Possibly he relied on the younger Joseph Koger to read and write English for him plus gave him other responsibilities.
The younger Jospeh Koger would have been about 11 years old when his name appeared on the 1760 plat.Our society generally treats its 11 year olds as children and would probably not have a child's name placed on an important document.
Back in the 1700's eleven year olds were treated different than they are today.It was not considered unusual for an 11 year old to have a job.Ten year olds could be found on board naval vessels as part of the crew.Some served in the armies, mostly as drummer boys.
Reverend Richard Bryan served as a Methodist minister in Colleton District, SCduring the late 1700's and early 1800's.His marriage recods indicate Thomas Beech married Nancy Costine on 25 Feb. 1802.Reverend Bryan made a note that indicated "that the 25th of May next Nancy will be 12 years old."
Our ancestors had a competely different attitude about 11 year olds than we do.
