Our line, drawn
The smallest chart in the estate, and the shortest answer to how far this line goes back: nine people, and then the doors close.
This is the whole of it: 9 people, 4 generations at the deepest point, and 5 branches that stop dead — and the stopping is the finding. Argentine civil registration is not open to the public, so the line runs into a wall the moment it crosses back over the Atlantic.
What holds the Argentine side up at all is one document: the 1908 ficha de enrolamiento, which names Pablo's father and mother and then stops. Everything above them would need a register this archive cannot reach from here.
The English side goes further on paper — the Taylors reach James, born around 1796 — and that is the archive's own reading of its own file rather than a new claim. The seven Taylor daughters who are not in this line are on that page, not this one.
The 5 walls, and why each one is a wall
Each box names the country after the place, in today’s borders — an anachronism this archive would rather admit than hide, since Canelones in 1791 was the Banda Oriental of the Spanish empire. Where a place cannot be assigned it is left alone: bare Rosario is Santa Fe in Argentina or Colonia in Uruguay and this register holds both, and bare Córdoba is the open question of whether Sancho came from Andalusia or Argentina.
The living are not drawn. The chart starts at Nuno Fernando Lerena, born 1924. What it would take to get past each of these walls is on Open Questions; the lines this family marries into are on the trees.
