Primary Source Confirmation of United Empire Loyalist Lineal Descent: The Jackson–McFadden–Carter Chain and the 1851 Canada West Census Discovery

This preprint documents the primary source confirmation of a ten-generation lineal descent chain from Hendrick (Henry) Jackson, a confirmed United Empire Loyalist (UEL Claim #1205, Loyal Rangers, Albany County, New York), to John Carter (b. 1982, St. Catharines, Ontario, Canada). The central finding is the identification and transcription of the Jacob Jackson household in the 1851 Canada West Census (Charlotteville Township, Norfolk County, Canada West; Public Archives of Canada microfilm 004108059, images 274 and 276), confirming Jacob Jackson (Farmer, born Canada, age ~52) and Eleanor Jackson (born Ireland, age ~54) as household heads in the exact township documented by the Niagara Settlers published genealogy, with four named children — Edwin, Emily, Harriet, and William — matching the Copeman family history record exactly. Eleanor Jackson's recorded birthplace of Ireland is independently confirmed as Eleanor McFadden (b. 1797, Armagh, Ireland), daughter of Stringer McFadden who immigrated to Upper Canada on the ship Alexander, June 1, 1817. The complete ten-generation chain — Hendrick Jackson UEL → Pieter Jackson → Jacob Jackson → Eleanor-Jane Jackson (Pick) → Ella Pick (Pratt) → Jenny Pratt (Copeman) → Agnes Copeman (Dominey) → Maxine Dominey (Carter) → Daniel Carter → John Carter — is documented with primary source evidence for each generational link, including Albany Dutch Reformed Church baptism records, Upper Canada land petitions naming Henry Jackson as Loyalist father, the 1851 Canada West Census household record, Lynedoch Cemetery gravestones, the Barnardo's After Care primary document confirming the Dominey line, and the Saskatchewan Government marriage certificate (George Samuel Carter × Edith Katurah Sissen, 1912). The research methodology applied is the Presignal Subtraction Framework: systematic elimination of unconfirmed hypotheses through sequential primary source verification, with all evidence explicitly classified as Confirmed, Strong, or Probable. This is a living research document. Version updates will be issued as new primary sources are validated, including the pending Melva Jackson 1986 manuscript (Norfolk Historical Society) and the Ontario District Marriage Register search for the Jacob Jackson × Eleanor McFadden marriage record (February 1819, Hay Bay Methodist).
