'… Richard Smith, b. say 1583 [footnote: Aged "about 84 years" on 2 February 1666/7 ("Medical Records of John Winthrop," Manuscript, 701, … cited by Harris, "Doubtful English Ancestry of Richard Smith", Register 143:243)], living Wethersfield in 1669 [footnote: See Jacobus, "Richard Smith of Wethersfield", The American Genealogist 25:126, for the 1669 reference to him "come 80 years."].'
Harris, in the Register article cited, indicates that the 1669 entry actually reads 'above 80 y', and uses a birth year of about 1583, based on the 1666/7 reference giving his age as 84.
