'HENRY LEONARD, Jr., born 14 June 1658, married HANNAH JOHNSON HOLDEN, died before July 1726.'
Note that the day and month of birth match those of a Henry born 2 years earlier, who died. It is assumed that at some point someone conflated the birth dates of the two Henry's and this conflated birth date was copied here. There is no citation for this birth date and it does not appear in the Lynn VRs.
