Anna Maria Susanna Blignaut (Gouws) - Wrong father?

Anna Maria cannot be the daughter of THIS Gert Stephanus, as he would have been 3 years old when she was born.

I found records for a Gert Stephanus, married to Johanna Greef that more closely match the dates to have been the parents of Anna.
I've attached the links.
Johanna Carolina Greeff
Gert Stephanus Gouws, e3f1

Also, find the death notice for Gert Stephanus - with mention of his first wife Hannah Greeff

He died in 1893 at age 85. Thus born circa 1808
