with apologies ... "John Neal" is simply a memo for an ancestry.com member DNA match to me. William Joseph Waller's sister was Sarah Waller, who was my 2nd GGM.
If you are researching this line, email me at neil.millikin@gmail.com and perhaps we can compare some notes, etc.
From GEDmatch (FG265101C1) it seems we do not directly match, however our matches in common are like a bullet list from my most active research segments.
