400 years or so
One of our goals is to identify and document the first two to five generations from Thomas and Margaret where generation two would be the grandchildren. In his first book, Dr. Frank mostly covered some of these persons and Samuel's line down to the generation of Dr. Frank's father.
The Mayflower Society has books out to five generations. The data is not complete as I have verified. However, they are now focusing on two generations at WikiTree: Project:Mayflower. That was nice to see actually, as this society has been working for a century. Early on, I noted that Dr. Frank was not complete with his view of two generations, a 100 years ago: The kids.

10/24/2019 -- Notes in Vita Brevis article briefly touch on some technical (statistical) issues, such as incomplete data (actually, the reality of this type of work). I would add another. It's a conflation of information about more than one generation and is more of a cultural view than that of nature. It would be interesting to separate out the three groups: elderly, mature, and child. For the last, I would use Richard More (uncle). The first, Brewster comes to mind. The computer (and its ability to hoard (yes) will allow all sorts of studies - to wit, data science). Then, the idea would be to use the birth dates, when known, of the individuals. Some of these would be, it is noted, before 1620.
