Do these names ring any bells?

I wonder if, among your readers, there is a family member, relative or simply a good friend, who can tell me something about any of the individuals mentioned below. They all had a genus named after them.

Name Genus Family Author Date published
G Berrisford Berrisfordia Aizoaceae L. Bolus 1929 (?)
R A Rabie Rabiea Aizoaceae N.E. Br. 1930
E Stoeber (?) Stoberia Aizoaceae Dinter & Schwantes ?

This information is needed for an update of the late Prof WPU Jackson’s (1990) Origins and Meanings of Names of South African Plant Genera. The only information I have discovered about these individuals is that the species name of Berrisfordia is khamiesbergens, so maybe Berrisford lived in the Northern Cape; Rabie was a priest, (a missionary?) living around 1927-1930 in South Africa or Namibia; and Stoeber lived in Lüderitz, Namibia”

Any information provided would be a contribution to South African botanical history. I can be contacted on 021 685 4953 or gascoyne@mweb,co.za or at 68A Dean Street Newlands, 7700 (Cape Town). Your help would be appreciated.”
