I am also a descendant of Abigail Bartlett, who married John Stebbins and later Jedediah Strong. I have been studying the family. Much of the online info is wrong, of course, and confuses our Robert Bartlett with the other Robert who came on the 'Anne' in 1623.
For your question re Samuel Bartlett, son of our Robert, I rely on noted historian/genealogist Robert C. Anderson, who in his series, 'The Great Migration Begins'says this about Samuel: "SAMUEL, b. say 1637; m. (1) Northampton 27 April 1672 Mary Bridgman (Pynchon VR 142); m. (2) by 21 May 1676 Sarah Baldwin, daughter of Joseph Baldwin (in his will of 20 December 1680 Joseph Baldwin bequeathed to 'daughter Sarah Bartlett of Northampton' (HamPR 1:246-247)"
Hope this helps. Email me if you would like to share more information about the Bartlett family.
