Please help me trace a certain Mr Holwald/Howald, he was a German who came to Namibia/SuidWes Afrika between 1883-1893 as part of the Schutztruppe. Unfortunately I don't know his name as well as where he was based whilst in SuidWes Afrika during the aforementioned time period.

He is the father to my grand father, born on in 1907 in Brakwater near Windhoek. My grand father is name is Wilhelm Kovaherero Kaangundue.

Kindly help me locate my grandfather's biological father and his lineage.
