Daniel Rudolph du Toit - Is there not more children for Daniel Rudolf du Toit

According to my information, he is on my ancestors on mom's side. Or can somebody direct me in the right direction if I am wrong

A. Francois du Toit – 15/9/1664 Getr. Suzanne Seugnet-1673
B6. Francois du Toit – 28/6/1699 Getr. Maria Therond
C7. Francois du Toit – 7/7/1737 Getr. Sara Bockelenberg – 19/12/1745

H1. Daniel Petrus du Toit – 4/10/1914 Getr. Wilhelmina Hendrina Versfeld – 23/6/1918 (my grandparents)

Then follows my mom's siblings and then my generation.

How do I add these profiles to my tree, without duplicating them on Geni?
