Cape Town Directories: [I checked for Butler, Shelley, Watson & Stidworthy]
1826:
Griffiths, John, public house, 10 Zieke Street
1828:
Shelley, Timothy, billiard house, 17 Ziekedwars Street [dwars means cross/intersected]
Griffiths, John, 21 St Jan Street
Stidworthy, Joseph, builder, 3 Marktplein
1830:
Griffiths, John, 15 Plein Street
Watson, G, Barrack Street
Stidworthy, Joseph, mason & ornamental plasterer, Totness Cottage.
I do not know if this means that they owned the properties, which is maybe why there is no ref for Butler? Maybe James Griffiths was John's son? Zieke Street links Griffiths & Shelley - maybe they were all neighbours??
Hope this helps
