Millards of Rehoboth, MA

Have just uncovered my Millard roots.
Am a descendant as follows:
Robert m. Elizabeth Sabin
Nathaniel Sr
Nathaniel Jr.
Rebecca Millard m. Henry Wheeler of Rehoboth MA
Avis Wheeler m. Benjamin Converse (CT)
Henry Converse m. Mary Mascraft
Emily Converse m. Jacob Wheeler of PA
and follows through to my mom, Edythe Wheeler.
I believe Robert's father was John.
Does anyone have information on John, birth,death, when he came to America? Also his family in England.
Would be very interested and grateful for any information and/or help. Also, if anyone else follows the same line, I would be interested in hearing from you.
Thanks much!
