I just learned of a 1689 census of the town of Bristol Massachusetts that names heads-of-household. John P. Demos mentions it on p.64 of his book A Little Commonwealth: Family Life in Plymouth Colony. I can't view more than a snippet, and I cannot find mention of this census trying several Google searches. I also tried searching a person reportedly named in the census under "Journals and Articles" at American Ancestors, but I didn't find an article transcribing the census. So I am hoping someone can point me to an image or transcription of this census available online somewhere.
Barry, Thanks for posting this information. It is very interesting. I made a free-space page for this, with links to the WikiTree profiles:
