No marriage found for a Samuel MANSFIELD.  Some assert Elizabeth's husband was Samuel MERRIAM, not Samuel MANSFIELD, for which marriage there is a record.  Locations are known residences of the husband, ending with the last known; none of which is necessarily the location of the marriage.

p. 102	...Tradition and family records inform us that Thomas Townsend came from London, and settled at Lynn, in the colony of Massachusetts Bay, about 1635, and as John Winthrop, his cousin, was governor of this colony, it is probable that his puritanical inclination caused him to select a home in New-England where many of his kinsmen and neighbors had emigrated a few years before.1  His wife was Mary, probably a sister of John Newgate or Newdigate, a merchant of Boston, who was born in Southwark, near London bridge, in 1590, and who in his will dated May 8, 1665, calls him brother-in-law, and leaves him a legacy of £10, to be paid him within one year after his decease. 1.  THOMAS TOWNSEND was granted 60 acres of land with the Lord Brook and others by the town of Lynn, in 1638, and he owned other lands near the iron works and at Rumney Marsh, Chelsea.  His town-house and lot of 7 acres was on the south side the mill street near the common, and next the Mansfiled property, and it was sold by his grandon Thomas, son of Andrew, to Daniel Mansfiled, of Lynn, July 25, 1702. He was made a freeman March 14, 1639, calls himself husbandman in his well-drawn deeds of gift to his children, and from his serving the public on more than one occasion, seems to have been an important citizen, and from papers bearing his name, and his beautiful autograph, now to be seen in the secretary of state's office in Boston, we have sufficient evidence of his ability.  He died in Lynn, Dec. 22, 1677, aged 83, and his wife Mary died of camp-fever, probably at the house of her son Andrew, Feb. 28, 1692.  They had:—   2.   i.   THOMAS, born about 1637.   3.   ii.   SAMUEL, b. in Lynn about 1638.   4.   iii.   JOHN, b. in Lynn about 1640.   5.   iv.   ANDREW, b. in Lynn about 1642.       v.   ELIZABETH, b. in Lynn about 1644; m. Samuel Mansfield, of Lynn, Dec. 22, 1669. 1A mass of circumstantial evidence to be embodied in a memorial volume when published has satisfied several expert genealogists and myself that Thomas Townsend son of Henry and Margaret was identical with the settler at Lynn.
