Hmmm
The 35-year-old fella' I regard as my son is called Dax. I got to know his mother when he was 6. (Long story - don't ask!). She told me that his name was an acronym for Diogenes Alexander Xerxes (but offered no explanation as to why someone living on a council estate in Sheffield should have any interest in Greek history!). While there are plenty of web references to the name 'Dax', none of them support that theory. (If it was true, 'my' Dax would be 'Alexander' twice over, since that's his middle name as well).
My own name (Christopher, which - in its full form - I hate) is probably derived from my mother's determination to 'move to a higher class'. She was an early prototype for Hyacinth Bucket. While born in the London Borough of Limehouse (at that time probably the poorest and most deprived community in England) and having 'entered into service' at an early age she was determined to emulate the lifestyle and aspirations of her employer (a Harley Street surgeon). That resulted in my name being chosen because it was reported, in early 1953, as being the most popular boy's name in the 'Births' column of 'The Times' ;-)
