This may or may not shed any light on the subject of William Viall of Charlotte County, NB. I was just looking at the will of a Rebecca Philips of St. Andrews dated 1796. She names her kinsman, William Viall of St. Andrews as the executor of her estate. This document further states that should William Viall die without heirs that this inheritance shall pass unto the hands of his sister "Nabby Kilby".
Lot 110 which had been granted to William Viall eventually comes into the hands of Ralph Taylor another of the Penobscot Loyalists.
