If you're still interested, I can give you a bit more info on some of the John Lamberson descendants. I am the daughter of Willard Neal Lamberson, a grandson of John Lamberson.
Willard Neal Lamberson md. Martha Morris Summers (I'm ashamed to admit I can't remember the year of their marriage, but I can probably find it.)
W.N. Lamberson left Huntsville to attend Georgia Tech around 1928. He was an architect in Atlanta from the 1930s until he died in 1986. He served in the Marine Corps in the South Pacific during WWII. Martha Lamberson died in 1975.
They adopted two children, whom they named John Ross Lamberson (b. 1952) and Mary Margaret Lamberson (me, b. 1956). Neither has issue. We both live in Atlanta. I was always told that "John Ross" was my great-grandfather's name.
James Gilbert and Joyce Baggerly Lamberson had one daughter, Ellen Estelle. She married Thomas Corker. They live in Newnan.
The "Annie L." Lamberson b. 1/1883 was Annie Lou. I met her once when I was very young. She was apparently quite a character, as people talked about her in awed and amused tones for years after her death.
