Re: The Barretts of Concord Massachusetts

I am descendant of Humphrey Barrett of England, Concord, MASS.It goes:
Humphrey
Humphrey, Jr.
Benjamin (m. Lydia Minott)
Benjamin (m. Rebecca Jones)
Benjamin (m. Sarah Merriam)
Joseph Merriam (m. Sally Green)

Robert (Bob) - can't find him
Lewis (Mary Toombs?)
Lewis, Jr. (Jane)
(I could have these backward/
information is scant-searching.
Someone in here married a Nancy)

Thomas Abraham (m. Cora Freeman)
Tommie Barrett (m Joseph Henry Hilsman)
. my grandparents

Does anyone have information that will connect and straighten out the Bob and Lewis Barretts noted above?

Thanks,
Joy
