If this profile is meant to be the Hendrik Prinsloo of Slagtersnek then he is incorrectly placed.
Hendrik Prinsloo was 32 when he was executed in 1816.
Therefore birth date 1784. His reported father here Willem passed away in 1781.
Hendrik with the correct dates was probably d5e4 the son of Marthinus and Maria Klopper
The confusion possibly arises because of the two Maria Kloppers.
