Other, more serious researchers would need to answer your questions. But, I would only state "Massachusetts Bay Colony" and not include other titles.
And, I was going to comment that we did not have "provinces" in our part of North America. But, I just looked up "MA Bay Colony" on-line and found references I had forgotten about:http://en.wikipedia.org/wiki/Province_of_Massachusetts_Bayhttp://en.wikipedia.org/wiki/Massachusetts_Bay_Colony

Different researchers refer to "Maine" before 1820 in different ways. I usually refer to the 1700's having "the Northern Territory of Massachusetts." But I was told recently that's not the correct designation. http://en.wikipedia.org/wiki/Province_of_Maine
(I notice a tiny mistake in that page. "New Brunswick" didn't exist until 1784. That land was part of "Nova Scotia" up until then. I learned that when I started researching my ancestor, Calvin KIDDER, b1765 NH. He had followed other NH families up to Canada ~1783. (He was not a Loyalist or Sympathizer but traveled with them - possibly because of a girlfriend at Age 18.) When I mention him in postings, it is easier for me to say he arrived in New Brunswick in 1784 - rather than trying to explain that in 1783 he was arriving in Nova Scotia.)
