Ngementu (M P M)

Mike Sandham's research log ("List 1"), imported 16 Sep 2026, credited to The South Africa War Graves Project unless his entry says otherwise: filled Corps -- each of these was EMPTY on this record and no existing value was changed. Derived fields recomputed inline where applicable.
16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo '97086219' was CLEARED. It was not a reading of this man's record. PersonNumbers 32245 to 32249 -- 5 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (32245, Ngcondo, Jim (M P)). 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.
Database-wide FirstName/Age contamination sweep (extension), 28 Sep 2026: FirstName 'Jim' and Age 21 were forward-filled from PersonNumber 32244 down a contiguous run of 3 records -- this record's own LastName ('Ngementu'), Initials ('M P M'), ServiceNo ('') and DateDeath ('1984-08-01') are all genuinely distinct, confirming a different real person whose FirstName/Age were simply never captured. Unlike the first pass of this sweep, Unit is NOT touched here -- it is not part of this contamination (see the Unit-restoration correction on the related run) and this record's own Unit ('Ciskei Parachute Battalion') is left exactly as found. FirstName and Age CLEARED; no replacement guessed.
