I cannot help you with John Wiswell Minott's parents, but he is not a son of Samuel and Martha (White) Minott. Samuel and Martha had 10 children recorded in the Putney, VT vital records. Their son John b. 7 Feb 1780 in Putney, went south to Clarksville, TN with his brother Thomas b. Oct 1774 and both died there. Thomas in 1790 and John before 1810.
