This Johan George Conradie (b. February 26, 1883, d. June 10, 1946) is evidently not the son of Johan Georg Conradie, c2d4e18, but is instead the son of Pieter Jacobus Conradie and Maria Magdalena Catharina Conradie (born van Wyk), i.e., a different family.
The evidence for this is in the source: https://www.familysearch.org/ark:/61903/1:1:QGLV-LF84 (referenced in the "Overview" section), which is his death record and which lists the names of his parents and immediate family..
Could the profile manager(s) please correct his profile accordingly?
