MacKenzie , Herbert Eric (H E)

4 Sep 2026: Regiment leftover "South African Army" cleared -- that's the service branch (Army, as distinct from Navy/Air Force), not a specific regiment; the actual unit ("Services School") is already captured in Unit. Per John's decision, the 52 records with no better Unit info were left as-is.
16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo 'P/21084' was CLEARED. It was not a reading of this man's record. PersonNumbers 41537 to 41561 -- 24 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (41537, Joubert, Cornelius Johannes (C J)). A value repeated down an unbroken block of PersonNumbers is a forward-fill import artefact, not men who shared a service number; the pattern holds across 850 such runs on this roll and is independently confirmed by Mike Sandham's research log, which attaches such numbers to the head of the run 167 times against 6 contradictions (all examined). No replacement is guessed: this man's real service number is simply not known, and a blank field says so honestly where another man's number did not.
8 Oct 2026: CONFIRMED CONTAMINATION, CORRECTED. Initials "C J" cleared and set to "H E" -- they belong to Joubert, Cornelius Johannes (41537, three rows above); this record's own FirstName is "Herbert Eric", which "C J" never matched. Found while processing Graham's 8 Oct post for this record. Rank "Sergeant" filled (was blank), per Col (rt) Graham du Toit Last Post, 8 Oct 2026. Unit "Services School" left as-is; Graham only names "the South African Army" (the parent organisation, not a conflict).
