My name is Alex Shaw (oldest son of Melinda Tingle Shaw)and believe we may have some common ancestors.
My grandfather was William McKinley Tingle, son (from a second marriage I believe) of George Marion Tingle.Bill was born in the northern half of Alabama around 1927 (eventually settling in Central Tennessee)and his grandfather was named George Washington Tingle.
Although George is a fairly common name, in my approximation the dates do line up, leading me to believe that this may be the George Washington Tingle that you mentioned.I think this makes him my great great great grandfather....
I just started looking into our genealogy, so I apologize that I can't be of much help at this point.However, I hear that my Great Aunt, Marie Tingle, did some research years ago and I am hoping to get more details when we visit her in Lawrenceburg, TN at Christmas.
Please let me know if any of this sounds familiar or if you have gotten any more information since your last post and I will do the same.I know that several of my grandfather's brothers had names of presidents (William McKinley, Benjamin Harrison, etc.) and George Marion Tingle may have been a carpenter (a family trade perhaps).
