FYI the McLaughlins were well known to be related to Meriwether Lewis back in Pittsburgh.I do believe the Meriwethers and Lewis received a large land grand in Wilkes County GA.
The McLaughlins were boat builders in Pittsburgh.So were the Lewis and Clark families.
I believe everyone on the boat was related to Sacajawea and her two granddaughters Barbara and Margaret Myers or at least to Pocahontas or her sister Cleopatra. Cleopatra was a well known Indian name before Columbus.The Floyds of Sgt john Floyd were said to be related to Cleopatra.Some records suggest Montazuma's daughter was named Cleopatra. I guess you have to be Morman to understand this.
The Myers family in Pittsburgh were Jewish boat builders and were well know to build boats for General George Rogers Clark the brother of William Clark.
General John Myers is listed in the book Randolphs of Virginia. They named Fort Myers in honor of his father. Pocahontas is also in the book as well as Thomas Jefferson.
This is a tough line as CSA Col Meriwether Lewis Clark married to Abby Churchill aligned himself with CSA General Robert E Lee marred to Mary Anna RANDOLPH Custis during the Civil War.
You will find the records related to the Myers family of Ft Myers in Lee County Florida are directly connected to Jacob Myers the Pittsburgh boat builder.
