Andy's census appears to be the right one. She continued to live in Vicksburg until 1874, when she married Colin Reed and moved to Pennsylvania, where she had several children and then died in 1885, apparently in childbirth as she and her infant are buried in the same grave.
This is what I have so far. Just starting to look at her offspring's descendants, but I know some of them moved as far as California.

I'm confused by the 1901 publication date on her book. Was it compiled and published after her death?
I'm a bit confused about the death of Colin M. Reed - My brother was named for him - Colin Reed McNeeley, and I remember visiting someone in Pittsburgh and "Uncle Colin" was there. My brother was born in 1948.
