I am looking for information on the parents of Hester Petronella Frederika Potgieter, born 3 October 1854 and her sister Sara Johanna Potgieter. Hester married Carl Friedrich Wilhem Appel and her sister Sara married Carl's brother August Simon Friedrich Appel.
Hester and Sara were born in Uitenhage, therefor I assume that their parents lived in Uitenhage at that time. Hester's father might be Hermanus Lambertus Potgieter, as her second son was named Hermanus Lambertus. Unfortunately there are numeroous Hermanus Lambertus Potgieters. I couldn't find one from Uitenhage.
