Abram J Brinson, Heard family of Screven Ga

I am looking for information about the George Heard family. George was born 7-28-1828 Maine, died 1-03-1896 Screven Ga and is buried in the Scarboro cemetery in Jenkins Co along with his wife and children. His daughter Junietta, or Junie, was married to Abraham J Brinson, b 3-03-1851, d 6-30-1918.

My interest in this family is the connection between George Heard and my husband's Miller family. My husband's 2great-grandfather was Andrew Lewis Miller b 3-09-1809 Tn, d 8-27-1865, who is buried in the Cornelius Burke Cem near Rocky Ford in Screven Co Ga. also buried there is his brother William, b 1811 Tn, d 1873 Screven Ga. After A.L. Miller's death, his widow Priscilla and younger children lived with William. When William died, George Heard was named executor of William's will. I am not sure what the relationship was between George Heard and these Millers. One thing I am trying to find is the maiden name of George's wife. She was named Maria Louise or Louisa and she was born 1-29-1829, d 7-04-1903. The connection could be with her rather than her husband.

George Heard was in Georgia by 1850, listed as a schoolteacher in a Brinson household in Burke Co Ga. He became quite successful, and ran first a sawmill and then a brickworks in Rocky Ford.

Any information would be greatly appreciated.
