An unbroken descent in the male line from Siward, Earl of Northumbria, to a boy born in Austin, Texas in 2022. Every division is marked. Every gap is named.
Scroll to follow the line. Branches run out to the side and stop. Any name opens its record.
Robert Tyndall of Tansor I had two sons. The elder, William, took the manor of Tansor and half the presentation to the church. The younger, Robert, was settled by covenant in 1287‑8 and founded the line that continues. This is what became of the elder brother.
That pattern was not looked for. It fell out of the records once they were set end to end: at every point where this descent divides, it continues through the son who inherited nothing and had to go somewhere else.
The two remaining gaps are archival rather than evidential. One is a Tudor will at the National Archives that no one has yet pulled. The other is a Virginia county whose records burned in Richmond in 1865.
A note on the name. The family took its name from the valley — Tynedale, in Northumberland — and it is spelled here de Tynedale while the name is still locative and the family still northern, then Tyndall from the move to Tansor. The clerks who wrote the records varied constantly: Tindale, Tindal, Tindall, Tyndale, and on one American headstone Tindoll. Adam’s own seal matrix reads SIGILLVM ADE DE TINDAL, which is how the name sounded before the Great Vowel Shift moved it toward the modern Tyne. Those are scribal renderings of one name, not separate families. It is set here as Tyndall, which is the form the family has carried and the form it carries today.
The four living generations are shown by the names of the house, not their own: Björn, Siward, Waltheof and Uhtred, each numbered from the first of his name on this line. Compiled by Waltheof III, Austin, Texas. The documentary reconstruction preceded all genetic testing. Y‑DNA places the direct male line at R‑Z40708, coalescing in the late thirteenth century — the same window as Richard and Robert at Tansor — with surviving matches in the Northumberland and Cumberland border country under the surname variants Tinlin and Tinning. Upstream the line runs narrow and unbranched to R‑Z40722 at approximately 550 BCE, and beyond that to the Bell Beaker population of the Netherlands. Autosomal testing returns a concentrated English signal in the Nene valley of Northamptonshire, corresponding to the Tansor holding documented from 1247.
