Research notes
*** THE ROW THAT OVERTURNS THE NEGATIVE OF AN HOUR EARLIER. *** Father of MARTHA DU PLESSIS (PER-000750), and a son of Jean Prieur du PlessisM (PER-001905) and Marie Madeleine MenanteauM (PER-001906) - THE SAME COUPLE who are the parents of Charl Prieur du PlessisM (PER-001903). So Jean Louis and Charl Prieur are BROTHERS, and MARTHA AND DANIEL DU PLESSIS ARE FIRST COUSINS. LEAD-0272 tested for siblings, found none, and drew the wrong conclusion from a correct answer.
