What do we think? I extracted a chart from the article:
Fiske, William Wyman (2004). "The Probable English Origin of George1 Jacob(s) of Salem, Massachusetts". The American Genealogist. 79: 3–12, 209–17, 253–59. The American Genealogist. New Haven, CT: D. L. Jacobus, 1937-<AmericanAncestors> Page 6. Chart.

I guess my reaction is that TAG doesn’t publish articles they don’t believe are genealogically sound. However, the author is clear that more evidence is welcome.
