I can't imagine it as a name at all. Except on an actual Saxon, who would then have his/her own name anyway. And apart from that, I'm a proud UCT graduate - University of Cape Town. In its early years, before it became autonomous, it was the South African College, which in its turn had grown out of a boys' school called the South African College School and known as Sacs. And some of the songs that got sung at rugby matches went right back to those distant days: one of them began 'The SAC is the College for me, the best in the country round', and a few rather livelier ones referred to us as the Saxons, often featuring merry puns about sex ... No, not a human name, but good memories!
