While researching, the earliest Knoblauch/Knoblock in Georgia was found in 1767 in St. George's Parish. A hundred years later, some of his descendants fought in the Civil War in Florida.
I have not discovered the parents of Amanda Noblock; therefore, I cannot assist you with any information.
There was a marriage located of a William McCleland who married a Elizabeth Noblock on 03 Feb. 1826 in Screven Co., GA.
This is the perfect opportunity to mention that to join the Mayflower Soc., one has to only document their direct lineage to the Mayflower ancestor, and that it is not necessary to document the ancestor who does not have Mayflower heritage.
Since it is unknown for sure if Amanda Noblock was a wife to Zoath/Zoeth, she does not have to be documented for membership into the Mayflower Society.
I am sorry I was not able to help you, Brad. Good luck in your researching.
