Stan, Helen Dortch was so much younger that she also helped build B-17s as an "older" employee of some Lockheed plant down in Georgia during WW2. Check it out at:

“I’ve been an assembler and riveter for about two years and have never lost a day from work, or been a single minute late. I will quit only when the last battle flag has been furled on land and sea.”

– Helen Dortch Longstreet quoted in The Atlanta Journal;
Oct. 12, 1943

"Helen Dortch Longstreet, known as the “Fighting Lady,” was a champion of causes ranging from the environment to civil rights. In 1894 she was appointed Assistant State Librarian, making her the first woman to hold office under Georgia’s state government. At age 34, in 1897, Helen married 76-year-old General James Longstreet, second in command to General Robert E. Lee in the Civil War.

"n 1898, Helen was appointed postmaster in Gainesville, reportedly the first woman to hold this position in the state. When Georgia Power and Railroad Company announced plans to build a dam at Tallulah Gorge, Helen traveled the state, rallying others in her opposition. Her other causes included women’s suffrage, advocating civil rights for African-Americans, and promoting the establishment of the Georgia State College for Women in Milledgeville. Helen’s legacy is remembered today with the “'elen Dortch Longstreet Trail System' in Tallulah Gorge State Park."

Yeah, she was quite a lady, but I've never heard she helped fill in any "blanks" in the general's memory in his memoirs. One thing I do recall, he loaned his papers to R E Lee upon the latter's request, and I don't believe he got them back. Which may have contributed to some of the problems with JL's memoir.
