My name is Margaret Anne Harlan (Moore) and Ida Barrs Able was my grandmother. Eston Brooks Barrs, her father, was my great grandfather. One of the Barrs family members related to me sent me an email with some incredible information on the Barrs family history that I feel may be helpful to you. This man has an incredible website about the history of everything related to the Barrs family. His email address is: albarrs@wfeca.net.
The website address link is: http://albarrs.wix.com/usandfamilyhistory
Included in his email to me was the following message. Since it mentions a John Barrs, I am copying what he sent into this email and sending to you. Hope you will find this helpful.

Good morning Maggie;

Yes, so far as I can determine my North Carolina Barrs family is related to the South Carolina Barrs family. Both came from Warwickshire England. However, we have been unable to definitively connect the two line directly with Christian names, but I do know there was a Barrs relative, a John Barrs, a farmer, who lived in SC in the 1800s, came to visit his "cousin" James C. Barrs, my GG Grandfather at Barrsville, Columbia County, FL in 1872, I believe it was, and was shot along with GG Jim Barrs in James C. Barrs' General Store. GG Jim lived but John Barrs died a couple days later. It's all in my Barrs e-books and e-articles on my Website. You are welcome to have a look at http://albarrs.wix.com/usandfamilyhistory

Get back to me if you have further questions that you can't find answers for in my Website...

Enjoy,

Al Barrs
