The following is from a RootsWeb submitter and completes the apparent connection of your Harold (Joseph1, Daniel2, Samuel3, Benjamin4, Jedediah5, Jedediah Clapp6, Taylor Smead7) to Joseph Estabrook/Eastabrook & Mary Mason.However, anything from Family Search or RootsWeb needs to be VERIFIED!Joseph and the two Thomas Eastabrooks and their descendants are often confused (and may be here) and conflicting reports are often posted/published so do use this information as a roadmap but check out all the info yourself.I haven't verified any of this and am just passing it along.
Benjamin Estabrook, b. 1744 in Sudbury, was the son of Samuel Estabrook, b. 18 Aug 1710 Lexington, Middlesex, MA, and Abigail (Flagg?).
Samuel was the son of Daniel Estabrook, b. abt 7 Jan 1674 (or 10 Feb 1675?), d. abt 1727-1735 prob. Sudbury, MA, and Abigail Flint, b. 11 Jan 1673 Concord, md. 21 Nov 1701 Concord.
Daniel was the son of the original immigrant Joseph Estabrook and Mary Mason.Joseph was born c1640 in Enfield, Middlesex, England, d. 23 May 1711 Watertown, Middlesex, MA, and md. 20 May 1668 to Mary Mason, b. 18 Dec 1640 Watertown, Middlesex, MA, daughter of Hugh Mason. Some people state that the immigrant Joseph was the son of Joseph Estabrook, b. c1608 Devonshire, Eng., and Anna Brainard, b. c1610 London, Eng., but others believe that is incorrect, however, I haven't verified that one way or the other.
