Another possibility is Nancy Millard. Potential parents of Nancy Millard could be Jean Allery Maillard and Anne Marie Mingo/Menego/Menegeaux. Was there a daughter Nancy
(or Ann(e)) in this family? I know this Millard family was settled at Bayhead, NS.
UPDATE: Autosomal testing indicates a number of matches to Jean Allery Maillard and Anne Marie Menegeaux as parents of Nancy. I believe Nancy was this couple's daughter Anne Maillard, b. 25 February 1786 at Lunenburg, Nova Scotia.
