Thanks Tom. By "JHM" do you mean the Mayflower Families through 5 Generations, Vol 23, pt. 3, John Howland? If so, that'll be my next lookup request. I have only 3 volumes and a poor local library.
I have sourced the profile with the TAG article you cite, and am working on the Yarmouth VRs. There is also a later TAG article I'm working on now.
