Elizabeth Green(e) 1821 - aft 1885

I am once again posting this in hopes that I may sooner or later discover who the parents of my ggg-grandmother Elizabeth Green(e) Hannon were.
She was born in 1821, in either North Carolina or Tennessee. She is listed as being born in TN in some census records and NC in others. I feel that she was born in NC .. can't prove it, but its a gut feeling.
She married Thomas Warren Hannon in 1842 in Rutherford County, NC.
In the 1850 census they are living in Polk, Rutherford Co., NC and living near them is a H.B. Green born abt 1825 NC, with his wife and children, I believe his wife's name was Lovinia or Lavinia.
Also in the 1860 census, Elizabeth and her husband are living in Columbus, Polk Co., NC and living near them was a John Green born abt 1810 in NC ..wife Caroline.
I firmly believe these may be my ggg-grandmother's brothers.
Also, Elizabeth and Thomas left NC after the Civil War and went to Tennessee. It took me a while to discover where in Tennesse they went and why. Thomas Hannon had family living in Cocke County at that time. Interestingly there was a Jeremiah Green born abt 1811 NC ..living in Cocke Co., TN in the 1850 census.
If there is anyone who has ties to any of these Green family members, I would love to hear from you..possibly we can tie all these together.
Thanks for any help.
