The information that you stated all matches what I have on those families. Elizabeth Ingram Dodson had a twin brother John who died in the war. Supposedly there was one other set of twins in the George Dodson Ingram family.
The last thing I have on Albert J. & Elizabeth Dodson was that they moved to the Charlotte-Amelia Co., VA area sometime after the war. I do not know when either died. In the 1900 census they lived with son George (Amanda's brother) in Amelia Co.
Albert J. Dodson was s/o Byrd & Nancy Doggett Gregory Dodson. She was probably from Charlotte Co. but they married in Mecklenburg Co., VA. Byrd & Nancy are buried near the Laurel Grove community in Pittsylvania Co.
This is all I have. I have no immediate connection with any of these families.
