Hester Wheelwright (1640-~1699) was the wife of Judge Samuel Wheelwright. In his will, he left "one Negro Servant named Titus" to her, but she may have predeceased her husband.
In his Will dated Jan 30, 1700, Samuel Wheelwright stated that "I do give and bequeath unto Hesther my beloved Wife, all my Cattell of all sorts, with one Negro Servant named Titus, with all my Mouable estate of all sorts which is not hereafter excepted." The subsequent probate record includes a listing for "1 Negro man, at £20."
Bourne quotes this (p. 408) as "I do give and bequeath unto Esther, my beloved wife, all my cattle of all sorts, with one negro servant named Titus," stating her name as Esther rather than Hesther.
