Re: Newton Lawrence Waller
I descend from Green Bradford Waller also. Newton married Narcissus Marginia Randall. She was a sister to my gr-grandfather Herbert Littleton Randall. My grandfather called her "Aunt Sis".
They lived next door to my grandparents in MS. The two families are neighbors in the 1920 census.
There is a site on Flickr that has about 6 pics of the family. If you are interested, I can probably find the site again.
I also have a pic of Green Bradford Waller.
