State journals very likely have a smaller readership, but in New England these journals do publish much original research including English origins and 17th century genealogy. From the New Hampshire Genealogical Record:
"The English Ancestry of William Chadbourne of Kittery, Maine" vol. 10 (1993):101-114, and "Additions and Corrections to the English Ancestry of William Chadbourne of Kittery, Maine" both by George F. Sanborn, Jr., FASG vol. 10 (1993):167. A google search of "Robert Chadbourne" "Margaret Dooley" (William's true parents) yields 229 hits. "William Chadbourne" Winchcombe (the wrong place) still yields 401 hits, but substituting Tamworth (the correct place) and one gets over 700 hits.
"Sarah Waters, Second Wife of Nathaniel2 Sanborn of Hampton, New Hampshire" by Clifford L. Stott vol. 13(1996):145-151. A google search on those two principle names yields 350 hits. Substituting Rebecca Prescott, Nathaniel's first wife, the hits jump up to 966. Adding all three names in quotes, yields only 10 hits.
"English Ancestry of Michael and John Brawne of Dover, New Hampshire and York, Maine" by James R. Brann, vol. 18 (2001):1-5. A search for "John Brawne" and "Berry Pomeroy" (the village in Devonshire whence he came) yields only two hits. Substituting Michael for John yields only one hit.
