Littleton G and William H Hammett.
Found information on George. Thank you to all who responded to my queries!
Now, I'm looking for the brothers of George. Littleton G has not turned up anywhere, and neither has William H.
I find them at a young age in a 1850 Heard County census.
Where did they go?
Approximate birth dates for them are:
Wm H - 1843
Littleton - 1849
