2a.  There is speculation that the first two "children" are not children, at all, but Thomas and Ann being re-baptized into a new church, but if so, I would think the baptisms would be done, if not on the same day, then at least about the same time and probably prior to their marriage.

2b.  William Henry ELDRIDGE.  1915.  Henry Genealogy, .  Press of T.R. Marvin & Son, Boston, MA.  It is said that on p. 55, Thomas Henry and Ann Thomas were married in Boston,  6 Jul 1710, by Rev. Cotton Mather.  The marriage bans of 22 Jun1710 reads "Thomas Hendry of Gt. Britain"; her residence is given as Boston.  This book contains errors — caveat emptor!

2c.  Anon.  1898.  A Report of the Record Commissioners containing the Boston marriages from 1700 to 1751.  City Doc. No. 150, Municipal Printing Office, Boston, MA.  Said to contain the marriage record of Thomas and Ann.

2d.  Chandler Robbins.  1852.  A History of the Second Church, of Old North, in Boston...  John Wilson & Son, Boston, MA.  Said to contain information regarding the names and birthdates of the children of Thomas and Ann.
