I found (in a family study):
”Winburg is a classic Free State town. [- - -] orphanage (estab.1902)
[- - -] are built along tree-lined roads which radiate from the town square.”
So Winburg orphanage was established in 1902.
Is it possible to find out who were placed there in the 1900's and 1910's? Are there any records still existing..?
