This tree doesn't appear to have any correct dates according to the: Will of George Cadman, husband of Hannah Hathaway; who died in 1718-1719, and who therefore could not have possibly been born in the years indicated, nor could his daughter Elizabeth Cadman White.
Also, his will clearly lists the names of his grandchildren - all children of his only child Elizabeth Cadman and her husband William White. The names of his grandchildren do not match those listed on this profile. At the time the will was written (1718) his grandson George (and therefore Elizabeth's son) is not of the age of twenty-one, meaning he could not have been born earlier than 1698.
See the following, which can be viewed online for possible clarifications:
The Mayflower descendant:
a quarterly magazine of Pilgrim genealogy and history, Volumes 21-22
“George Cadman married Hannah Hathaway daughter of Arthur Hathaway and Sarah Cooke and settled in Dartmouth Mass. He made his will 24 November 1718 and it was probated 6 January 1718/19. The inventory was dated the third of the tenth month called November 1718 and was sworn to 6 January 1718/19 but it is certain that December should have been written on the inventory instead of November first because in Old Style dating the tenth month as shown by its name was December not November which was the ninth month, secondly because the will was not made until 24 November 1718 and the inventory of course could not have been taken three weeks before that date. George Cadman therefore died between 24 November and 3 December 1718.”
This will goes on to say the Elizabeth Cadman White, wife of William White was their only child.
And George leaves various properties to his grandsons, Roger, Christopher, George, William, and granddaughter Sarah.
