William Henry Keys

Married JOHANNA CATHARINA MOUNTJOY, baptised at Burgersdorp on 29 February 1860 — a daughter of George Mountjoy and Maria Sophia Botha, which this archive had been asking about and can now answer. Eight children baptised across Dordrecht, Barkly East and Barkly West between 1878 and 1898: Robert Byron, William Henry, JAMES JONATHAN, George, Lancelott Byron, Cecil Frederik, Rachel Anna Maria and HERKLAAS EDWARD JOHANNES. The Mountjoy forenames crossing into a third surname, exactly as the Barry names crossed into the Daschners — and BYRON twice, which appears nowhere else in this archive.

The thirteen Mountjoy childrenThe NamesakesThe Register

  • 17 Sep 2026 — The Burgersdorp sweep of images 605–818 found five new people
    Three. Johanna Catharina Mountjoy, born 28 January 1860, was already held in full — a daughter of George Mountjoy who married William Henry Keys — and the sweep only confirmed her and gave her a reference. Frederick Fortunatus Werdmuller was already held from a 1907 petition and a 1953 estate; what the sweep added was his birth and his mother, which is a real gain and not a new person. THE DUPLICATE PERSON RECORDS WERE CAUGHT BY THE BUILD'S OWN NAME-COLLISION CHECK for the first and by reading the register for the second, before either reached a page. The rule it costs: a sweep that returns a name is checked against the archive before it is called a find. Where it stands →

The documents

…Twice more in this stretch, and both times to other families. And the one that was not a find at all Johanna Catharina Mountjoy, born 28 January 1860, has been in this archive for days — a daughter of George Mountjoy and Maria Sophia Botha, baptised on a leap day, and the woman who married William Henry Keys. She is one of the thirteen Mountjoy children. The sweep reached her from the other direction and returned the same two dates. That is a confirmation and a citable reference, and it is not a discovery. The duplicate record this sweep created was caught by the build’s own name-collision check before it reached a page.…

A dossier is every mention of a person anywhere in this archive, gathered automatically after the site is built and linked back to the page it appears on. Identity here is by NAME, not by resolved individual — where two people share a name they share this page, and the archive says so rather than guessing. Nothing on a dossier page is new evidence; it is the same evidence, brought together.
