Presumably born after 19 Nov 1660 since not named in grandfather Richard Sparrow's will of that date. Her brother Jonathan's birth was recorded in 1665, and Elizabeth married in 1684, so we presume she was born before Jonathan. Wills of her aunt and uncle Thomas and Sarah (Bangs) Howes show she was not yet 20 in Jan 1675/6 (born after 1655) but was of age by 26 Feb 1682/3 (born bef. 1665), and the birth of her brothers John 2 Nov 1656 and Jonathan 9 Jul 1665, all suggests she was probably born some time between John and Jonathan (i.e., 1657-1664). Since she did not share in the inheritance from Gov. Thomas Prence, she was probably a child of Rebecca Bangs, not of Hannah Prence.
