Would this not be her?

For the Gertruida Margrieta Sophia Putter I find is born 1874 - while Gertruida Margaretha Putter was born 1859 and a much likelier candidate as her mother.

Furthermore, Stephanus Jesasa Schoeman could not have been her father for he was only born 1889 (if this profile is correct - Stephanus Jesaja Schoeman) - 6 years after her birth.
However, that profile has Gertruida Margaretha putter born 1860 as wife, which also seems far-fetched if his dob is 1889.
Bothersome that if we change the parents to Gert Christoffel Schoeman and Gertruida Margaretha Putter, assuming the tree upwards is correct, her (Elizabeth Helena Catharina Schoeman) maternal line goes to Geertje Aeltje Gerritz, SM/PROG, who have a different mtDNA haplogroup than the tester.
