Some of the early arrivals, such as Higginson, wrote about their experiences. Then, there were the later lookbacks by others, like Conant.
The first researcher who wrote about the early times of Massachusetts was Rev. William Hubbard. And, he mentioned both Thomas Gardner and John Tylly. Was he the first? The Reverend wrote in the late 1600s. Luckily, the only copy of his work was saved by those who knew how.
Later, there were other lookbacks, such as Felt's who went through the records of towns, such as Salem and Ipswich and others.
Then, with the advent of organized work on records about mid-1800s, families started to put together their stories. We have the works of Frank A. Gardner, MD in this category. As well, there was a flurry of activity around the 300th anniversary of the Cape Ann venture.
Now, we're almost 400 years out. It's time for another go-around. See Vol. I, No. 3 of Gardner's Beacon for our view of Margaret's perspective.
Expect that there will be a continuing threads on this, and related, topics.
