Barrett [409] Hannah, da of Capt. Jonathan and Mary, [born] March 26, 1812.
There are two marriages in Malden VRs that could be this Hannah and there is no other Hannah Barrett born in Malden that would match either. A Hannah Barrett m. 1833 Henry T. Rich with death and census records calculating a birth somewhere in the range 1810-1812. Another Hannah Barrett m. 1836 John S. Newhall death and census record shows her birth over then range 1806-1812. Since both these marriages occurred after the father's probate, neither husband appears in the probate file. Neither death record identifies the parents of the respective Hannah, though the second one lists the birthplace as "Dartmouth" making the wife of John Newhall a less likely candidate. However, without more evidence, this is just name matching.
