Juanita:I have yet to find Samuel's death date.The only ones who appeared to have stayed in Nova Scotia were son Jeremiah and daughter Hannah per my notes below.Sorry I couldn't help further.
BIOGRAPHICAL: Samuel Bancroft and his children joined the pre-royalist migration, going into Annapolis County, Nova Scotia, about 1761 or a little earlier."Samuel Bancroft came here with his father and brothers and sisters, who all shortly afterwards returned to their old home in Massachusetts, except Hannah and Jeremiah.The former married John Starrett, of Granville, and the latter settled near Round Hill." ("History of the County of Annapolis," Calnek and Savary, p. 47.)Calnek states in his manuscript record (of which a copy is in the Library of the New England Historic Genealogical Society): "They were highly respected members of the comunities in which they have domiciled, as they have always maintained a character for industry, honesty, loyalty and religious deportment."
